VOICE CPU hd6415108F system manages 64 voices polyphony based on QS Composite Synthesis subtractive synthesis. A basic program is composed by 4 PCM each with individual settings:
- volume gain
- pitch tuning
- stereo panning
- polymode or mono with portamento
- zone assign
- effect amount.
WAVETABLE is a 16 MB ROM at 48 kHz categorized into 16 groups + 1 extra GM bank especially designed for Midi files SMF play.
SAMPLE IMPORT the module imports 16 bits samples (WAV or AIFF also old SDII Digidesign Sound Design format is supported) using the Soundbridge which is a free bundled software that burns special 2/4/8 Mb flash cards.

PERFORMANCE QS mix mode manages 16 parts individual parameters:
- 13 assignable velocity curves
- Midi channel
- volume
- pitch/octave shift
- stereo panning
- effect level
- wheel modulation effect
- sustain effect
- keyboard zone.
THE TRACKING GENERATOR
allows to track some note steps for some short loop sequences.
FILTER each player part features 1 lowpass filter with no resonance.
Specail Filter track parameter increases or decreases filter cutroff effect through octaves.
TIP: The effect Q-resonance emphasis emulates a kind of resonance.
ENVELOPE there are 3 EGs:
- EG1 amplitude: 4 stages ADSR+ 1 extra segments on initial delay time and sustain decay time
- EG2 filter: 4 stages ADSR + 1 extra segments on initial delay time and sustain decay time
- EG3 pitch: 4 stages ADSR + 1 extra segments on initial delay time and sustain decay time
The special trigger mode determines if the EG should be reset from beginning or continue according to 4 different modes: normal, freerun, reset and reset-freerun.
LFO a single delayed digital modulator for each layer (shapes: 8 shapes : sine, triangle, square up, saw up, saw down, noise and 2 random models).
There are 3 modulation destinations:
- LFO to amplitude
- LFO to filter
- LFO to pitch.
EFFECT based on Quadraverb II DSP featuring 4 real-time stereo effects including: reverb, chorus, pitch shifter, flanger, delay, overdrive and leslie.
TECH: Effects parameters can be controlledd by Midi CC#.
MIDI Internal parameters are easy to modulate with the internal Matrix and each part can assigned to Midi CC#. Full sysex support for both editing and librarian storing purposes.
MEMORY:
- 512 preset slots
- 128 Mix Mode (400 Preset, 100 User).
RAM can be expanded using S-RAM memory cards, now quite difficult to find out on the market.
Battery replacement: soldered lithium battery Br-2325 model.
MODIFICATION QSR can be mangled with CIRCUIT BENDING PROCESS for glitched and lo-fi random sounds. The lack of space generally involves an external case or extra rackmount unit.
