64 step sequencer / 99 save slots / 4 Drum Tracks / 4 Multi-touch Pads / 3 Signal generators per voice; Noise, Click and Tone / Frequency modulation (on pads 3 and 4) / Amplitude modulation (on pads 1 and 2) / Delay unit (with infinite looping capabilities) / EQ on each Tracks / 5 send effects (distortion, delay, reverb, bit crush, chores/flanger) / 2 master out effects (Soft clip, 4-pole low-pass filter) / Mixer.
DrumSynth is an “old” App now. When it was released there was not so many Drum Machine Synthesizer in the App Store like we have now. It's still a good App, a very good one because of the generated sound more than the available features. Only 4 tracks, no Midi, no Song Mode…
