Here we go ............... (Thanks to Steven Collins for the loan of the SQ10 !! 8-)) Here's what I know of the Korg SQ10 : - 3 X 12 Channel Analog sequencer, pot adjusted. The pots are a *nightmare* to set up. Each note has to be individually tuned. Channel 3 is normally reserved for the note length. - Channels 1 & 2 are effectively connected to a single CV/Gate output. A switch allows the sequencer to sequence these channels in a few different ways : (1) Channel A . Stop (2) Channel A Channel B Stop (3) Channel A channel B Channel A Channel B ..... free-running (4) (5) (6) All the above, except single-stepped with a push button. This is most useful for tuning each note. Channel C runs in time with the other two channels. It's CV output can be routed to the sequencer clock CV input, effectively controlling the on-time for each note. This means that the note on time for note 1 of channel one is the same for not 1 of channel 2. - Beside the sequencer mode switch is the (large) Tempo adjust knob. It can be made to run *very* fast!! - Gate signals can be extracted for each note, the idea being that the last note of your sequence Gate signal is sent to the reset input, thus defining the sequence length. - There is a portamento knob for each of channels A and B. Both channels have a +-1V , +-5V switch, for switching the range of the two banks of 12 pitch knobs. - Duty Cycle is adjustable (1 knob only) for the gate output signal. - The sequence can start/stop from an external foot switch, or single-stepped. - The instrument itself, is about 14" wide, by 8" high and 4" deep. It's black, with white lettering, and there are three distinctive rows of 12 knobs across the front of the instrument. - Input / Outputs (as far as I can remember) : CV out. Channels A & B gate out. 12 Gate out signals (for each note) Reset Sequence input. Sequence start/stop input. Tempo input (CV). Single step input. - There's a neat little 2-channel mono mixer built in. This is accessible from three 1/4" jacks on the front panel. It just sums the two inputs and sends them out. I think this is about it. Everything, including sockets, is on the sloping front panel of the machine. It also has a neat bunch of LEDs, one for each note of Channels A and B (none for C). There's a tempo LED, too. At the moment, I'm using it to sequence a Yamaha CS5 and a CS15, paralleled together. -- Regards, Peter ----------------------------------------------------------------------------- | M O T O R O L A B .

What did they > look like, what was possible, etc etc. There were quite a lot of analog sequencers at one time: the Korg SQ-10 - type, with one pot for each step. A counter stepped through the pots, so you could set a different voltage (=pitch, frequency or anything else) for each step. A portamento feature was usually included. The SQ-10 had 24 steps, but could run as two channels of 12 steps each (or less, selectable). A third channel could provide a third control voltage in this mode. Sequencers like this were built in to some monophonic synthesisers: the Yamaha CS-30, and a Buchla synth (which I don't remember the name of) spring to mind. Tangerine Dream once had a variant of this type designed for them, where they had rotary switches instead of pots. Pots have the disadvantage that it's awkward to set accurate pitches, unless you have perfect pitch or something; a stepped selector like a rotary switch makes this easier, also meaning you can easily change the sequence while it's running. A few years ago I built a more digital sequencer, where the control voltages are stored in a memory chip, like the ones used in microcomputers. The voltages are stored as values 0..63, with two bits being left over for gate and legato functions. A D/A on the output converts the binary values to a voltage. There are four parallel channels on this machine, three drive D/A converters and a fourth has a digital output for plugging into my Pro-One-rebuild. I'm sure sequencers like this must have been made on a commercial basis as well (the EMS Synthi 100 sequencer springs to mind, but it wasn't produced in large numbers) but I can't think of any one at the moment. The step from a digital sequencer to a microcomputer controlled one is small; the Roland MC-4, MC-8, CSQ series and MSQ series are all microprocessor based, which gives additional functionality as well as the ability to save sequences on disk or tape. Unless you wan't to build a true analog sequencer with pots or rotary switches, the hassle of designing the digital electronics for a digitial hardwired sequencer is probably not worth it these days, compared to designing a simple microcomputer based system, and then programming it.

It's basically the same concept as the SQ-10 described, but in a 16x4 configuration with an attached touch keypad. There's one touch-sensitive metalplate and accompanying LED under each column of knobs. When the plate is touched, the sequence jumps to that column and resumes from there. There's a wide variety of retriggering options, and the voltage from each row is provided as a seperate output. You can clock the thing externally, and very quickly, like at audio frequencies. There's a *random* mode. -Randy [comes and goes like the wind, footloose and .sigless] From analogue-request@magnus.acs.ohio-state.edu Mon Jul 26 20:14:26 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA20045; Mon, 26 Jul 93 20:12:16 -0400 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from goren1.u.washington.edu by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA20040; Mon, 26 Jul 93 20:12:14 -0400 Received: by goren1.u.washington.edu (5.65/UW-NDC Revision: 2.28 ) id AA25942; Mon, 26 Jul 93 17:12:03 -0700 Date: Mon, 26 Jul 93 17:12:03 -0700 From: Romeo Fahl Message-Id: <9307270012.AA25942@goren1.u.washington.edu> X-Sender: palefox@goren1.u.washington.edu To: analogue@magnus.acs.ohio-state.edu, dacc@cmp-rt.music.uiuc.edu Subject: Re: Analog sequencers Status: O I noticed that you said that Buchla still _makes_ these sequencers.

Well, lessee...there's the several different Serge sequential voltage sources, which come in varying amounts of stages between four and eight, and you can get them with or without onboard quantizers. These are Nx3 sequencers, not unlike the keyboard sequencer but w/o the touchplates and a lot smaller. Then Buchla has a touchplate + sequencer device that's similar to the Serge model that I've seen on UIUC's Model 200. Buchla also makes an 8x3 sequential voltage source that's on the 100 I should be getting in a few weeks, and since there's a Series 100 version of this, there's most likely a Series 200 version, too. Then EML also has a "something-like-a sequencer", the Model 300, which is a _weird_ box that has 16 calculator- button pads, plus 16 knobs for setting the different voltage levels that correspond to each pad, then there's an onboard LFO/clock that steps thru all of this if you set it for that. The EML 300 is a weird beastie, and I've only seen one, in use as a controller for the Moog 900 here at UIUC. Besides those, well...there's the Synthanorma, which I don't know anything about, and the Geiss Matrisequencer, which I also don't know anything about. Any takers on explaining these two devices?
