Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- New sound shaping on the Analogue voice
The square wave gains a pulse-width LFO with its own speed and depth, for classic PWM movement.
Sine, triangle and sawtooth gain unison spread, the same detuned-copies effect the Morphing oscillator uses, each with its own LFO.
Both default to off, so existing presets and sessions sound exactly as before.
- Voice sheet
The Analogue waveform selector is now a full-width row of four large buttons instead of small grey glyphs, with the selected shape filled.
The parameters below it follow the waveform: pulse width for the square, spread for the others.
The oscilloscope and slider cursors move with whichever LFO is running.
- M channel
Both touch strips now start unassigned and show an Assign label. Touch one to pick its destination from the seven available.
Assignments persist across relaunches, as does the strip you clear.
Snap has a checkbox beside its label so it reads as a latch, ticked while engaged.
The Assign button is outlined rather than filled, matching the other buttons in its row.
- Fixed
Tutorial pages for the dice, umbrella, clock and waveform controls spotlighted nothing. All four highlight correctly again.
- Other
The in-app user manual is rewritten to match the current interface.
New app icon.
