Just a short post that I hope will find its way into the search engines in the hopes that it helps someone in the future. My Ensoniq SQ-80 stopped making any noise a month or two ago. As it turns out, I ran into an RTFM error. Except that I bought this synth second hand and didn’t have TFM.
Earlier today, I was on the excellent Buchty.net Ensoniq Resource page and found not only a PDF of the original Musician’s Manual, but several other manuals and schematics as well. Had I been smart, I would have scanned through it first. I went the long way, but in the interest of Internet time, here’s a choice bit from page 18 of the user guide:
IMPORTANT NOTE: If you don’t have a CV Pedal plugged into the SQ-80, you should NOT leave this parameter set to PEDAL=VOL when you turn the unit off. If you do. the next time you power it up, the SQ-80 will set the “straight synth” volume to zero — it won’t make any sound. To get the volume back to normal, just go to the MASTER Page, select this parameter and set it to PEDAL=MOD.
Of course, I took the long way around and, in fairness, would not have turned to the Master Settings page information first. But once I knew where I was looking, there it was!
It’s been a long time since my Ensoniq OS chops were strong, but I’m glad to have this synth back in the mix!
