Turquoise DS

Turquoise DS is a 3x3 drum synth. Tap or hold pads to create sounds and rhythms. Each pad triggers a separate synthesizer which can be endlessly tweaked and adjust to taste.

Drums, bass, tones, abstract synths, sound effects and all kinds of sounds can be created for each pad. The entire kit can then be saved as a preset. Includes a number of factory presets and space for unlimited user presets.

User Guide




Presets are stored in a file called "TurquoisePresets.plist" in the documents folder. This can be accessed through iTunes. You can export the list as a backup or import a different preset list from your computer.


At any point press RECORD. The RECORD button will change to RECORDING and audio will be recorded to the file TurquoiseRecording.wav.

Press RECORDING again to stop recording.

After you have stopped recording you can press the LOAD REC button to load the recording for playback.

Press PLAY to hear your recording. While your last recording is playing you can press RECORD and overdub your last recording.

This process can be repeated to layer and build on your recording.

The COPY FROM REC button will copy your last recording to the iOS clipboard. The audio can then be pasted into another app or even back into Turquoise.

If you have previously copied audio to the clipboard from another app pressing PASTE TO REC will paste it to Turquoise’s recording file.

After pasting into Turquoise you must press LOAD LAST REC to cue the audio for playback.

Press the SAVE REC button to give your recording a new name and save it to the Documents folder available in iTunes.

The last recording made is called TurquoiseRecording.wav and is available for export in iTunes App File Sharing


When used in Audiobus, Turquoise defaults to 2 voice polyphony in order to run well within the 256 frame default buffer size of Audiobus. If Audiobus is switched to the optional 512 frame buffer size a higher polyphony can be used. The polyphony in Audiobus can be adjusted in the app settings for Turquoise.

When run as a stand-alone app Turquoise always uses full 9 voice polyphony.

The row of lights at the very bottom marked SELECT indicates the currently selected sequence. Touch any light to select that sequence. The currently selected sequence is the one that will show in the main grid area above.


The matrix section allows you to patch the Filter ADSR Envelope from any pad to the Pitch, Filter or Resonance of any other pad. Each pad section is labeled at the top. Slide up or down on a number to change the modulation amount.
