Microtuning Features:

• Internally loads and externally receives both MTS (MIDI Tuning Standard) Bulk Dump and Single Note Microtuning Files.
• Operator ratios can easily be set to values that are coincident with the microtuning being used, thereby producing tuning related FM sidebands in the timbre of the instrument.
• Isoharmonic spacing of the operator ratios.
• Precise values may be set for microtonal pitch-bends.
• Arbitrary microtonal period shifting makes it possible to pitch transpose in both octave and non-octave increments.

FM-RM Oscillator:

• 4 Operator FM Synthesis with Ring-Modulation.
• 57 Operator Algorithms.
• 11 different Operator Waveforms.

Phase & Pulse-Width Oscillator:

• 22 Waveforms.
• Phase & Pulse-Width LFO Modulation.
• Envelope Generators
• 6 independent Envelope Generators dedicated to modulating Operators A-D, Filters and VCA.
• Velocity sensitive.
• Keyboard tracking.

Filters

• 2 State Variable Filters with 12 and 24 dB response.
