Percussa micro super signal processor

So it’s a day of slightly strange apps. First off Ringabell AU, and now PWM-2 mini. Which is apparently a synthesizer which is designed to work well on a small screen. The developer seems very keen to furnish us with very specific technical details. So here are the details:

Specification

Voice mode

8 Polyphonic, Monophonic

OSC (Oscillator)

Wave form:
Sine, Triangular, Sawtooth, Rectangular

Seasoning:
PWM (Pulse Width Modulation)

OSC2:
Detune, Note, Volume

Option:
Portamento

LFO (Low Frequency Oscillator)

Modulation target:
OSC2 Pitch, PWM Width, LPF Cutoff

LPF (Low Pass Filter)

Cutoff can be modulated by EG out

EG (Envelop Generator)

Parameter:
Attack, Decay, Release

BPM sync delay

Parameter:
Send, Time, Depth

Time:
3/2, 1.0, 3/4, 0.5, 3/8, 0.25, 3/16, 1/32, 1/48

Step sequencer

1.) 8 steps x 4 ch mode(*1) Using 1, 3, 5, 7

2.) 16 steps x 4 ch mode(*1) Using 1-2, 3-4, 5-6, 7-8

3.) 32 steps x 2 ch mode(*1) Using 1-4, 5-8

4.) 64 steps x 1 ch mode Using 1-8

(*1) Timbre is applied to all channels with the current parameter

MIDI

Supported:
NoteOn, NoteOff, AllNoteOff,
Start, Stop, Resume (For operating sequencer)

Support Inter-App Audio (Generator only)
Timbre that can be stored is 24

To receive MIDI on PWM – 2 mini, Camera Connection Kit and MIDI device (ex. USB MIDI Interface) is required.

Not to bad at all really. Of course there’s a few features they’ve left out, for which they ask forgiveness.

  • Send MIDI data
  • Change parameters by receiving MIDI data
  • BPM synchronization by receiving MIDI data

PWM-2 mini costs $1.99 on the app store now:
