Synister

Three oscillators (each with a choice of pulse, triangle/saw and noise waveforms), all three of which can be modulated in a bunch of different ways. For every oscillator, you can modulate the volume, pan, coarse tuning and waveform shape with up to two modulation sources (three LFOs, three envelopes and various external sources like velocity, modulation wheel, aftertouch, etc.). Needless to say, this means that you can program some seriously complex patches without ever leaving the oscillator panel.

Next up are the three envelopes (one ADSR for volume and two ADSRs for modulation) which sound very snappy and which also let you modulate the envelope speed with up to two modulation sources. It is also possible to fine-tune the attack, decay and release curves. Awesome stuff! The three available LFOs are equally cool, allowing the user to modulate the speed of each LFO and apply a fade in to the LFO signal.

Filter: Synister comes with two of those, offering four modes per filter (LPF, HPF, BPF and Ladder) and, once again, up to two modulation sources for the cutoff and resonance parameters. As all other modules, the filters can be turned off in order to reduce the CPU hit. Speaking of which, Synister is a very well optimized synthesizer and at behaves very well both in terms of stability and CPU usage.
