* 64 voice polyphony.
* 3 Additive Oscillators per voice: Each multi-waveform oscillator has its own volume / frequency (pitch) envelope.
* 3 Multi-mode Stereo Filters per voice: Each filter has 23 different filter types and 18 different distortion types. Filters can be connected in three different configurations: Series, parallel and split.
* 4 Modulators per voice: The modulators can be used as LFOs (low frequency oscillators) or audio rate oscillators to modulate other modulators, multi-mode filters or the additive oscillators. Each modulator has its own envelope.
* 2 MIDI LFOs: These 2 LFOs are used to generate MIDI CC (control change) messages to modulate plug-in parameters. Since each controller can be linked to multiple plug-in parameters, it is possible to modulate all of those parameters at the same time using the MIDI LFOs.
* 2 32 step Patterns: The patterns could be used as waveforms for modulators or MIDI LFOs. Since the number of steps is user adjustable, it is possible to generate patterns in rhythms other than 4/4 such as 9/8, 7/8, etc.
* 16 Step Arpeggiator: Every step has its own volume, length and delta. The number of steps is user adjustable, so it is possible to generate arpeggios in rhythms other than 4/4, such as 9/8, 7/8, 5/8, etc.
* 8 Band parametric EQ/Filterbank: The EQ could be constructed in different combinations such as parallel, series, or input + series. Each band in the EQ could be bypassed, which makes it possible to construct a very flexible parametric EQ.
* Stereo Echo / Delay: The echo effect has feedback and filter cutoff parameters, and its delay size is tempo synced.
* 16 Band Vocoder: The vocoder uses analog modeled bandpass filters. Either the synth output or the audio input can be used as carrier/modulator signal for the vocoder.
* Stereo Chorus / Flanger: The chorus effect in SynthMaster has separate delay and rate controls for the left and right outputs, which widens the stereo width of the effect output.
* Stereo Reverb: The reverb effect in SynthMaster is based on physical modeling. You can specify physical parameters such as the room size, the distance of the left & right sound sources, and the width between the sound sources.
* Microtuning: Each plug-in instance can have its own custom tuning specified.
* MIDI Links: Plug-in parameters can be easily linked to MIDI controllers. Each plug-in instance has its own parameter-controller link settings.
* "Partial" Presets: Plug-in parameters for various parts of SynthMaster can be saved independently, which makes it very easy to create complex presets by combining different "partial" presets.
