iSyn Poly has 3 studio-quality synthesizers and a drum machine.

Each synth is a full-featured analog modeling synth with three oscillators, a classic 24 db/oct ladder-style lowpass filter, independent filter and amp envelope generators, and full modulation routings.

The sample playback drum machine has 8 simultaneous instruments arranged into eight user-selectable drum kits and an editor page allows tuning, panning, level and decay time for individual instruments.

It also has a sequencer:

• Four track sequencer with piano roll and automation editor.
• Record what you play live with the onscreen keyboard/drum pads or using an external CoreMIDI compatible keyboard.
• Real time quantize function and metronome for recording.
• Arrange your songs with variable length patterns ( 1 - 99 bars ). Move and copy/paste patterns.
• Recording and playback of X/Y Pad movements, modulation wheel, pitch bend and key velocity.
• Full set of editing functions with unlimited undo.
• Modeless gesture optimized editing.
