CAVIT SEMAI VIRTUAL INSTRUMENTS
Professional iOS Sampler, AUv3 Host and Live Performance System for iPhone and iPad

One App. Every Instrument. Every Sample. Every Performance.

Cavit Semai transforms your iPhone or iPad into a powerful professional instrument. Designed for keyboards, synthesizers, MIDI keyboards and MIDI controllers, it combines professional sampling, AUv3 instruments, SWAM, synchronized loops, advanced performance algorithms and microtuning in one platform.

From a sample to a playable sound

A multisample supplies the recordings. A Combi track determines how you play that sound. A setlist button recalls the associated combination.

1. Open App Settings using the gear.
2. Open Sample Manager. Use an existing multisample or import your own recordings.
3. Return to the setlist. Press and hold the desired button for about one second to edit it.
4. Enter a name and open Combi.
5. In the desired track, choose Cavit Semai → Multisample, then select your sound.
6. Check MIDI Input and select the source you want to play from.
7. Open Edit Sound, adjust the sound and save it. Also save the finished combination and the setlist entry.

Three separate save operations: Sample Manager saves the sample library. Sound Edit saves the track sound. Setlist configuration saves the name, color and other button settings.

iPhone: The main app screen is designed for landscape orientation. Rotate your device accordingly. This help preview also adapts to narrow portrait screens.

iPad: The main screen is also designed for landscape orientation. This help displays more content side by side when enough space is available.02 · ORIENTATION

Recall and edit setlist buttons

A setlist button is a saved entry for a song, sound or combination. Distinct names and colors help you recognize entries while performing.

Recall a saved entry

Tap the button briefly. The app recalls its settings and sends the configured MIDI data. For an entry configured for loop playback, the button can switch playback on or off.

Create or change an entry

1. Press and hold the desired button for about one second.
2. Enter a distinctive name.
3. Choose a color.
4. To switch an external instrument, set MSB, LSB, PC and Channel to match that instrument.
5. Open Combi to edit the tracks for this entry.
6. Save the button configuration with Save and confirm the prompt.

Field or button	Meaning
Name	The label you recognize in the setlist.
Color	A visual aid, for example for instrument groups or songs.
MSB / LSB	Bank selection for the external instrument. The connected instrument determines which values are required.
PC	Program change within the selected bank. Some instruments display program numbers differently; check their program-change table.
Channel	MIDI channel for the program change.
Only Combi	Uses this entry only as a combination. The separate bank/program-change transmission of the setlist button is not performed.
Transmit	Sends the configured data so you can check the result on the destination instrument.
Combi	Opens the selected button’s combination.
Save	Saves the button settings.

Swipe through the setlist pages if the desired button is not on the current page. Use Sort Setlist Buttons in App Settings to edit the order.Before major changes: Export your setlist. An unsaved name or button setting is not a reliable backup.04 · COMBINATIONS

Combi: use several tracks together

Edit setlist button → Combi

A combination groups several tracks. Each track can have its own sound assignment and settings.

1. Check that you are editing the correct setlist button.
2. Open Combi and choose the track you want to configure.
3. Choose the sound source. Use Cavit Semai for internal sample playback.
4. Check the track state. Play indicates an active track; Mute indicates a muted track. Tap to switch between them.
5. Set Volume to an appropriate level.
6. Test the combination via MIDI and, if needed, with Transmit.
7. Tap Save and confirm Saving Combination.

Transmit and Autotransmit

Transmit sends the MIDI settings configured for the combination. Autotransmit toggles automatic transmission. Sending MIDI settings does not replace saving the combination.

iPhone: Work through the tracks one at a time. Scroll the track area if all settings are not visible at once.

iPad: Use the larger track area to compare volumes and sound assignments across several tracks.05 · SELECTING A SOUND

Select Cavit Semai in a track

Combi → Desired track → Cavit Semai

1. Open the Cavit Semai menu in the track.
2. Open Multisample. If a sound is already selected, the menu may show Multisample: [Name].
3. Tap the desired entry. Selecting it activates playback for the track.
4. Open MIDI Input and choose the appropriate MIDI source.
5. Play a few notes and check volume and key range.
6. Open Edit Sound to change tuning, velocity response or effects.

First selection: If no MIDI input was previously configured for this Cavit Semai track, selecting a multisample initially assigns Cavit Semai Ensemble High. Check this assignment and change it if you want to play from another source.

What does Stop Cavit Semai do?

Stop Cavit Semai stops the notes on this track and removes its Cavit Semai sound and MIDI-input assignments. To silence the sound temporarily, use Mute.The message Keine Multisamples im Sample Manager (“No multisamples in Sample Manager”) means you must first provide a sound in Sample Manager.06 · SAMPLE LIBRARY

Use Sample Manager

App Settings → Sample Manager

The screen is titled Sample Sound Editor. Here you manage the multisamples used by your Combi tracks.

Create a new multisample

1. Tap Add New Multisample.
2. Enter a meaningful multisample name and tap Next to open Edit Sample Zones.
3. Import WAV files or a Korg KMP multisample. Import methods are described in the next chapter.
4. Check the sample zones and save your edits.
5. Save the library with Save before leaving Sample Manager.

Edit and audition existing multisamples

Tap an editable multisample in the list to open its zones. Use Play to audition samples. For multisamples with several samples, the preview advances to the next sample; an indicator such as 1/8 helps you follow it. Stop ends the preview.

Select several multisamples

Tap the checkboxes next to the entries. Select All selects all multisamples eligible for batch actions; tap it again to clear the selection.

Action	Result
Export Cavit Semai Set	Exports selected eligible multisamples as a sample set.
Import Cavit Semai Set	Reads an existing sample set into the library.
Loop On	Enables loop settings for selected multisamples in a batch, where the data allows it.
Loop Off	Disables loop playback for selected multisamples in a batch.
Trash	Removes selected deletable multisamples. Check the selection and confirmation carefully.
Save	Saves the sample library.

Protected content: In this project version, factory sounds and protected purchased multisamples cannot be edited or selected for batch actions in the same way as your own multisamples.

iPhone: The creation button may be labeled Add Multisample. Some long button titles are shortened; the functions are the same.

iPad: The creation button is labeled Add New Multisample. Use the larger list to select multiple entries.07 · SAMPLE FILES

Import samples, assign zones and set loops

Sample Manager → Multisample → Edit Sample Zones → Sample zone

Choose the right import method

Button	When to use it
Import WAV	For your own WAV recordings. Import in the zone editor also supports automatic mapping; check the resulting assignments.
Import KMP File	For individual Korg KMP files. Their associated KSF files must be accessible.
Import KMP Folder	For a folder containing KMP files and associated KSF subfolders. Especially useful when the file provider limits subfolder access during single-file import.

1. Tap the appropriate import button.
2. Select the file or complete folder in the file picker.
3. Read any prompts and wait for the import message. The app shows progress for larger folders.
4. Check the resulting zones. Importing a folder can create several multisamples.
5. Save your edits. If folder import has already saved automatically, check the completion message and the entries in Sample Manager.

Key Low, Key High and Root Key

Key Low is the lowest key in a zone; Key High is the highest. Root Key is the original pitch of the recording. The sampler uses it to calculate pitch changes for other keys. An incorrect Root Key can put the sound out of tune.

Set the ranges to cover the keys you need. Use overlaps intentionally only when you want several zones to sound together. Also check the velocity range if a zone should respond only to certain playing strengths.

Audition the sample and loop

1. Open the individual zone in Edit Sample Zone.
2. Use Play Sample to hear the recording and Stop to end playback.
3. Enable Activate Loop if needed.
4. Set Loop Start and Loop End. The end must come after the start.
5. Use Auto-Loop-Finder as a starting point if needed, then audition the result.
6. For rhythmic recordings, Analyze BPM and loop-length settings are also available.
7. Tap Save and save the enclosing editing stages as well.

Practical tip: A loop should sound as smooth as possible when moving from its end back to its start. If you hear a click, move the boundaries and test again. Tap −/+ once for a single change; press and hold for continuous changes.08 · SAMPLE SETS

Export or import a Cavit Semai sample set

App Settings → Sample Manager → Export / Import Cavit Semai Set

Export your own multisamples

1. Select the user multisamples you want to export in Sample Manager.
2. Tap Export Cavit Semai Set.
3. The Export Selected Sounds dialog provides Target Device Import ID (optional).
4. For an export intended for another device, use that device’s import ID. Copy Device ID copies the current device’s import ID; Paste Device ID inserts a copied destination ID.
5. Check the displayed export allowance. An export for a specified destination device requires an available allowance. If needed, press and hold Paste Device ID for about 0.8 seconds to open the multisample export-code dialog.
6. Tap Export and choose the offered location or file-output method.

Sample-set files use the extension .cavitsemai. Without selected exportable multisamples, the app reports Nothing selected or Nothing to export.

Import a sample set

1. Tap Import Cavit Semai Set.
2. Choose the appropriate .cavitsemai file.
3. For name or file conflicts, the app displays Import conflicts.
4. Choose Import Conflicts as Copies to keep existing content and import conflicts as copies. Use Overwrite User Conflicts only when you intend to replace existing user content. Cancel stops the import.
5. Wait for completion and check the new multisamples in the list.

Device binding and protection: A device-bound set must match its intended destination device. Factory sounds are not overwritten in a conflict. Protected purchased multisamples cannot be exported.09 · TRACK SOUND

Cavit Semai · Sound Edit

Combi → Track → Cavit Semai → Edit Sound

This editor changes the sound of the selected Combi track. It is separate from Sample Manager: here you adjust playback and sound rather than manage the underlying sample files.

The six tabs in original screenshots

These pictures show the interface, not recommended sound settings. A layer labeled No Multisample needs a sound assignment before it can play samples.

Velocity/Range

Select a multisample and enable the layer. Velocity Low/High limit the velocity range; Volume controls layer volume. Low/High in Key Range limit the keys. On the keyboard, drag from the first to the last desired note.

Tuning

Octave shifts the sound in octaves, Transpose in semitones, and Fine Tune provides fine adjustment. Voice Mode sets the available playing behavior, such as Mono. Legato connects successive notes; Crossfade and Speed adjust the transition and its speed. Portamento creates a glide in pitch. Left and right Pitch Bend values apply to all layers.

LFO

Enable LFO and choose Target, Controller and Waveform. Rate sets the speed, Depth the modulation amount, and Phase the starting phase. Velocity Low/High specify the velocity range. With MIDI Clock Sync enabled, speed follows incoming MIDI clock and Division.

Amp · ADSR

Enable ADSR. Attack sets the time to reach full volume, Decay the subsequent drop, Sustain the held volume level, and Release the fade after releasing the key. Drag the knobs vertically. Double-tap to reset a value. The curve shows the resulting volume envelope.

EQ

Enable EQ. Low, Mid and High process low, middle and high frequencies. Gain boosts or cuts the band; Freq changes its frequency. Mid Q controls the middle band’s width: higher Q values affect a narrower range. The EQ curve shows the effect.

FX · Acoustic Model

The FX section processes this track’s layers together. Enable the effects you want to use. Acoustic Model provides model groups and presets, with controls for adjusting the model. Reverb, Delay and Distortion have their own switches and Mix controls. Saving model presets and saving the track sound are separate operations.

Edit layers

1. Check Combi Track at the top to ensure you are editing the correct track.
2. Select the desired layer.
3. Use + Layer to add a layer. Choose its multisample and adjust its settings.
4. Use Delete to remove the selected layer after confirmation.

The green or gray state indicator shows whether a layer is enabled. With several layers, always check which one is selected.

Tab	What you adjust	Typical example
Velocity/Range	Multisample assignment, velocity response and active key range.	Play a layer only in the upper keyboard range or with a stronger attack.
Tuning	Pitch, transposition and fine tuning.	Shift a layer by an octave or tune it slightly.
LFO	Periodic modulation of the sound.	Create regular movement and test it while playing.
Amp	Volume envelope and available sample-start settings.	Give the sound a softer onset or a longer release.
EQ	Boost or cut frequency ranges.	Soften a harsh sound or add presence.
FX	The track’s shared effects.	Add space or other available effects.

Change values and save

Change a parameter and play a few notes. Many sound parameters provide a live preview. Use − / + to change values step by step; press and hold for continuous changes.

The save icon in the header commits the edited track sound. Saved appears briefly and the editor stays open. The current integration also saves the track sound in the combination. If you then change other Combi settings, save the combination again.Cancel or the close icon exits editing. Unsaved live changes are reverted. Changes you have already saved remain.

Acoustic Model presets

The Acoustic Model preset section may offer Factory Presets, Model Presets and User Presets.

• Save: Save the editable user preset.
• Save as: Store the settings as a new user preset.
• Rename: Rename a user preset.
• Delete: Remove a deletable user preset.

Acoustic Model presets save the settings for that effect section. Saving the entire track sound is a separate operation. Use the save icon in the header to commit the current sound to the Combi track.

iPhone: The tab bar scrolls horizontally. Swipe it if a tab such as EQ or FX is outside the visible area. Scroll within the editor for more parameters.

iPad: The larger screen makes comparing parameters easier. Layers and tabs have the same meaning as on iPhone; additional parameters may still require scrolling.10 · SETLIST FILES

Export and import a setlist

App Settings → Export/Import

Setlist export backs up button entries and their saved combinations. Back up WAV and KSF sample files separately using sample-set export.

Export a setlist

1. Save the desired button and Combi changes first.
2. Open Export/Import.
3. Tap Export Setlist.
4. Enter a meaningful file name, for example including a date, and choose a location in the file dialog.
5. Complete file output and look for Export successful.

Setlist files use .cavitSetlist. Export includes the entire current setlist and its button configurations.

Import a setlist

1. Tap Import Setlist and choose a suitable file.
2. In Select Setlist Buttons, select the entries to import. Select All selects all offered entries; Deselect All clears the selection.
3. Continue to Choose Import Destination.
4. Choose one of the three methods. When inserting, also select a starting button.
5. Check the selection and destination, then tap Import Selected or Replace All, as appropriate.
6. For full replacement, confirm the prompt. After completion, check the message and the setlist.

Method	Result
Insert from a Button	Starts at the selected button and skips occupied slots. Example: start at button 5; button 6 is occupied; new entries go to 5 and 7.
Append to Existing Setlist	Adds entries after the last occupied button. Empty gaps before that button are not filled.
Replace Entire Setlist	Clears the current setlist and places selected entries at their original button numbers. Unselected positions remain empty.

Replace Entire Setlist also removes existing entries that you did not select. Export your current setlist first if you want to keep it. If there is not enough free space, import stops with a message without importing any entries.

iPhone: The import selection uses a compact layout for limited height. Scroll through the list and check selected names before continuing.

iPad: Import/export also opens full screen here. Content is centered; selection and methods work the same as on iPhone.11 · MIDI

Ensemble Mode and MIDI connections

App Settings → Ensemble Mode / Midi Device Manager

Ensemble Mode switches the virtual Ensemble MIDI sources on or off. The icon shows the state; a crossed-out icon indicates that the mode is off.

The sources are named Cavit Semai Ensemble High, Cavit Semai Ensemble Mid and Cavit Semai Ensemble Low. Select an available source in a Cavit Semai track’s MIDI Input menu.

1. Connect your MIDI device. For Bluetooth MIDI, first open Bluetooth Device Manager.
2. In Midi Device Manager, check that the required source is available.
3. Enable Ensemble Mode if you want to use the virtual Ensemble sources.
4. Open the Combi track and choose the desired source under Cavit Semai → MIDI Input.
5. Check the track state and volume, then play notes within its active key range.

Ensemble Mode alone is not sufficient: the MIDI input, active track, selected sound and key range must work together. The actual processing of High, Mid and Low depends on the app settings.12 · IPHONE, IPAD AND READING

When something does not work as expected

Problem	What to check
No sound from a track	Is a multisample selected? Is the track on Play? Is Volume audible? Is MIDI Input correct? Are the note and velocity inside the active range?
No multisamples in the track menu	Open Sample Manager, import or create content, and save it. Then select the track again.
Sample not found	The referenced sample file is missing. Check the original import and reimport the complete sample set if needed.
KMP import cannot find KSF files	Use Import KMP Folder and select the parent folder with the associated KSF subfolders. Cloud files must be available.
Sound is out of tune	Check the zone’s Root Key, fine tuning and the layer’s Tuning settings.
Some keys are silent	Check Key Low / Key High and Velocity/Range for gaps. Only certain zones or layers may be active.
Loop clicks or sounds uneven	Adjust Loop Start / Loop End, try Auto-Loop-Finder and audition. Check whether the recording is suitable for continuous looping.
Nothing selected during sample export	Select at least one exportable user multisample using its checkbox.
Sample-set import reports the wrong destination device	Check the set’s device binding. For a different recipient, export a set using that recipient’s import ID.
Not enough space for setlist import	Select fewer entries or choose a start position with enough free slots. Append uses only slots after the last occupied button.
External instrument changes to the wrong program	Compare MIDI connection, Channel, MSB, LSB and PC with the instrument’s bank/program-change table.
Changes disappear after closing	Use the correct save operation: zone, multisample/library, track sound or setlist button. Cancel does not commit new unsaved changes.
