C64 FOREWORD the SID is a 28-pin DIP capsule audio chip was projected in 1982 for the American 8-bits computer Commodore 64, simply the biggest home computer sale in the world ever.
The famous chip is a mixture of digital and analogue technology with phase accumulated oscillators and analogue multimode NMOS filter.
REMAKE Elektron made a Midi desktop version for musician enclosing the mythical chip in a silver box with full sonic control featuring and a high speed bus access; original SID produces a high noise-level, but the new design isolates some of this using dedicated buses - anyway but be prepared to gate many background noises.
VOICE machine based subtractive synthesis generates 1 voice polyphony (3 osc per voice) in monomode or 3 voices in polymode (1 osc per voice). The Sidstation generates 3 oscillators (5 shapes: triangle, saw, mixed, noise, pulse variable width) with variable parameters:
- ringmodulator: an oscillator modulates the previous one e.g: 3>2 - 2>1 - 1>3
- pitch detune
- delay start
WAVESCAN special wave cycling mode for sweeping sequences a bit like Korg Wavestation.
You can define loop points composed by various steps (up to 32) each with assigned parameters:
OSC 1 / 2/ 3 selection, note, filter mode, filter cutoff and length.
PERFORMANCE machine offers some special playmodes:
- legato with adjustable time rate
polymode play the oscillators in polyphonic way for chords, but they cannot be assigned to different Midi channels.
FILTER multimode resonant filter with cutoff range from 30 Hz to 12 kHz:
lowpass at 2 poles
bandpass at 1 pole
highpass at 2 poles
band reject at 1 pole
- mode all: activates all modes in the same time (weird).
ENVELOPE 4 EGs, 4 stages ADSR structure quantisized into 15 values:
- EG1 OSC1 amp
- EG2 OSC2 amp
- EG3 OSC3 amp
- EG4 VCF filter.
LFO up to 4 bipolar delayed assignable modulators with fade-in, variable depth and ABZ mode that change negative values into positive ones. All modulators are identical and features 7 shapes (tri / saw/ sqr/ ramp / rnd / S& H / flat output is set to a steady maximum value) in addition, 2 LFO can be combined for more complex waveforms. Here's the modulation matrix sumup:
||Modwheel / pitchbend / velocity / aftertouch / Midi CC# / another LFO
||cutoff / vibrato 1-2-3 / PWM 1-2-3
|| yes, dividers from half note to hemidemisemiquaver
MIDI all parameters are Control Changes mapped, also full Sysex dump implementation.
ARPEGGIATOR each voice features an individual arpeggiator.
SYNC arpeggiators, lfo and osc delay can be master synched to internal clock, or slaved to Midi according to 6 time- dividers from half notevalueto hemidemisemiquaver.
100 RAM patches
No ROM nor external card only computer Midi Sysex dump
SIDSTATION RELATED FAMILY:
SIDSTATION NINJA EDITION (50 units produced )Special limited black Sidstation edition with black case, blue leds and a different soundset, but essentially this is the same machine -overpriced as "collector" item.
