Korg 707 Synopsis

Strap-on DS-8

Voice architecture is similar to a dual oscillator subtractive synth (i.e. {DCO1->DCF1->DCA1}+{DCO2>DCF2>DCA). Ring modulation and two voice modes (poly and unison) are also provided

eBay Description

Key Features

1. Aftertouch: routed to DCO LFO, timbre, amplitude
2. Architecture Class: fm
3. Audio IO: headphones and 2 (stereo) analog outputs
4. Audio Source: DCO1 waveforms are saw, square, bright saw, and bright square. DCO2 waveforms are saw, square, and xmod (DCO1 crossmodulates DCO2).
5. Communication Interface: MIDI In, Out, Thru
6. Effects: delay (manual, long, short, doubling, flanger, chorus)
7. EG: DCO EGs are 6 element (3 levels, 3 rates) with polarity (each level), timbre and ampitude EGs are 5 element (2 level, 3 rate)
8. Expansion: Patch memory card (MCR-02 = 2 banks, MCR-03 = 4 banks)
9. Filter: "Spectrum" controls "resonance" (possibly a digital filter)
10. Form Factor: 49 keys
11. Key Scaling: routed to OSC, timbre, amplitude
12. LFO: routed to oscillator, timbre, amplitude (with delay). waveforms are triangle, saw, square, S/H

14. Multitimbral: 8
15. Pedal Inputs: 2 footswitch pedal inputs (portamento, damper, or patch change)
16. Performance Control: portamento pitch/timbre bend and volume/mod (Osc/DCA/DCF) wheels
17. Polyphony: 8
18. Power: 700mA 9VDC (- tip)
19. Released: 1987 1987
20. Sequencer: no
