Alesis 6461 Prototype Pics

Follow-up to this post. Some pics of the Alesis 6461 / QS6 in via Mike.

He recieved confirmation from Dave Bryce of Alesis that this was indeed the prototype of the QS6. The 6461 refered to 64 note polyphony and 61 keys.

Update: some pics of the inside.

"Looks like a 'nearly production' version as I see only 2 hand soldered jumper cables. Everything else looks neat. Even the PCMCIA card slot is there, even though there is no external plastic guide/surround."

Note the ALESIS S6 MAIN PCB REV. x5 dated 5-23-95 printed on the PCB in the 2nd to last image below, followed by a sticker found inside dated 9-5-95. It likely fell off a chip.

The QS6 was released in 1996, per Wikipedia: "In 1996, Alesis introduced the first of their QS series synthesizers. The first of these were the QS6 61-key synth and the QSR rackmount synth. Following these in quick succession were the QS7 76-key synth and the QS8 88-key synth"

  1. Eric Persing would very likely know details on this. He was doing presets and sound design for QS-series and from talking w/ him back in the day he was involved pretty early on.
