The original MS02 basically look like this : LOG AMP ANTILOG AMP ADDING AMP TRIG processor x2 2 pot 2 pot 2 pot 1 switch Freq tuning Freq tuning ch1 level reverse (+-) Width Width ch2 level 1 LED indicator 2 jack 2 jack 3 jack 2 jack Hz/V input OCT/V input (0~+15V) (-4 ~+4V) ch1 , ch2 in input (Vth +-2.5 v) OCT/V out Hz/V out out (-10 ~+10V) out (0 <- -> +15 v) (-12V ~+12V) (-12~+12V) (a simple analog mixer) Now for the LOG and ANTILOG you can be inspired by any OPAMP reference handbook .. but care should be taken (I guess) in order to achieve the same voltage reference of the MS02 (if you build one yourself, check the voltage value above ! ). If you don't find any log->lin or lin->log chips or diagagram I can try to make an ugly ASCI-matic .. (but check National and Texas handbooks first !) The adding amp is a simple analog mixer (I'm not sure why was there !?) , probably not needed for your purpose .. The (2) trig processors are very simple to build just one opamp used as inverter with the switch allowing polarity changes ... again care in using the appropiate voltage references .. Good luck .. The MS03 instead was a box similar to the ESP on the MS20 (a pitch follower basically, or a pitch->vco if you want ..) but it was able to drive both, Hz/volt and OCT/volt synths .. basically was used to control with guitar,brass,vocals a generic synth ..

With a little tweaking, the Korg MS-02 can be used to map EML voltages into 'normal' 1v/octave. That is my actual goal. I have an EML sequencer and 2 EML-101's, but I want the sequencer to drive other gear. It is too neat of a box to use just on the EML-101's. The sequencer outputs 1/10 of a volt per half-step. And the low octave is biased at around 2 (or 3, I forget) volts. So I need a circuit to transfer 1/10 of a volt per half-step into 1/12 of a volt per half-step and 'subtract' the 2 volt offset. out = (in - 2) * 10/12 I think this is a simple circuit, but I don't know that much about circuit design. I can read a schematic and fix things, but I don't have the background to design something new. BTW, I do have the NEC handbooks.

Crowell's message of Sat, 17 Apr 93 16:20:13 CDT <9304172120.AA01481@cmp-rt.music.uiuc.edu> Subject: Re- Re- Older Korg Synth Status: RO I will admit that these Korgs are just a bit before my time; the first piece of Korg gear that I have major familiarity with is the semi-modular MS-20, which is a very nice, very flexible piece of equipment if you dig into that patch panel some. Supposedly, there was a whole large _series_ of Korg MS gear; maybe Dan @ Korg could run down what was on it and which models there were, but I remember the MS-20, a simpler device called the MS-10, then there was something of an expansion module, an analog sequencer, and a vocoder, all of it in cases similar to the MS-20. Could even be more, who knows... The MS-series was some damned interesting stuff, and I really regret that I didn't spring for the one that a band I did sound for sold off back in '83 for $350. Hmm, let me see now.. The MS-10 has one oscillator, LP filter only one modulation wheel, noise generator, LFO and EG all patchable from the front panel via cords. The MS-20 is a far more interesting piece of equipment with two oscillators, LP & HP filter and more patch possibilities + a signal processor which converts pitch to CV/trig. Following the trend, the MS-50 should have 5 oscillators, but not so the case. I've only heard of the MS-50, but I think it has got only one oscillator, no keyboard, and a lot of strange :) signal modulators, in a sense an add-on "fun box" for the other MS synths. The MS synths have quite a characteristic sound. The filter(s) are very resonant, but doesn't give that grim "fly me thru that brick wall" Prophet steep, sharp cutoff. Interesting is that the MS-10 isn't just a stripped down '20, but rather quite a different instrument, with a somewhat richer sound (yes, with only one oscillator!) much due to the PWM which the '20 lack :-|. The two together are a powerful setup, but it's a real p* i* t* a* to program it :-) Favorite trick: Trig them from the signal processor of the MS-20, using a highly dynamic hihat (or whatever) sound as input source. It is then possible to make it trig in a random (but still rhytmic) pattern by carefully twiddling the sensititivity knob. If you're into sampling your own electronic drum kit, the MS-20 with lots of ring in the filter, and HP filtering of white noise is a treasure mine. It's funny though, here in Sweden these beasts turn up once in a while, at quite reasonable prices. The SQ-10 is a great device for increased creativity. It has 3 rows of 12 tone steps (controlled with voltage knobs). The 2 top rows are for melody, and the third for dynamics (to patch into VCF for instance..) You can also select between different ways the rows should be played in succession, and there are inputs for trig, start/stop and some CV inputs for altering the speed (instead of trigging it).

I picked up a Korg SQ-10 analog sequencer a week ago and feel I have to say something about it. It's great! The combination ms-20/sq-10 is quite powerful. The beast has 3 channels of each 12 steps. It can be put in several modes such as alternating between channel 1 and 2 , stepping forward one step when receiveing a trigger, playing a single channel with or without repeat when receiving a trigger. The later can provide some amazing effects such as an additional envelope with or without ramping between the levels. Ramping is achieved by adjusting the portamento knob. Wavesequencing effects can also be achieved by letting one channel modulate the pitch which gives you an arpeggiator and another channel modulate the high and lowpassfilter. If the portamento settings are zero then the result is abrupt changes in the filtersettings which gives a nice rhytmic feel, by turning the portamento settings up a little bit you get nice smooth continous changes in the filter frequencies and a sound which is very *alive*. Another thing I haven't tried yet is feeding an external signal thru the ms-20 (for example a distorted guitar) and then letting the sq-10 trigger the envelope which should be set to a fast attack and fast decay to a zero sustain. Then some interestig rhytmic amplitude modulation of external soundsources could be made. The machine is highly recommended! /Mikael Hillborg, Computer Science, University of Uppsala, Sweden From analogue-request@magnus.acs.ohio-state.edu Sun Apr 25 08:45 WET 1993 Received: from quark.magnus.acs.ohio-state.edu by sihp03.si.estec.esa.nl with SMTP (16.7/16.2) id AA15359; Sun, 25 Apr 93 08:45:06 +0100 Return-Path: Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA05259; Sun, 25 Apr 93 02:23:16 -0400 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from motgate.mot.com by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA05254; Sun, 25 Apr 93 02:23:15 -0400 Received: from pobox.mot.com ([129.188.137.100]) by motgate.mot.com with SMTP (5.65c/IDA-1.4.4/MOT-2.14 for ) id AA15607; Sun, 25 Apr 1993 01:23:14 -0500 Received: from comm.mot.com (il02dns1.comm.mot.com) by pobox.mot.com with SMTP (5.65c/IDA-1.4.4/MOT-2.14 for ) id AA00809; Sun, 25 Apr 1993 01:23:13 -0500 Received: from dub-tse (dub-tsw1.comm.mot.com) by comm.mot.com (4.1/SMI-4.0) id AA18671; Sun, 25 Apr 93 01:24:22 CDT Message-Id: <9304250624.AA18671@comm.mot.com> Received: by dub-tse (16.6/16.2) id AA05944; Sun, 25 Apr 93 07:19:39 +0100 From: Peter Cassidy Subject: re : SQ-10 Analog Sequencer To: ANALOGUE@magnus.acs.ohio-state.edu (Analogue Mail List) Date: Sun, 25 Apr 93 7:19:38 BST Mailer: Elm [revision: 66.25] Status: RO > > I picked up a Korg SQ-10 analog sequencer a week > ago and feel I have to say something about it. > It's great!

By routing channel C's output back to the clock time input, each note's timing can be adjusted. The only pitfall is that Channel A and B are tied to channel C so A's note duration is the same as B's. It's a bit of a nightmare trying to work out the timing, tho'. Channel C is also good for sweeping a VCF input in time with the CV in. -- Regards, Peter ------------------------------------------------------------------------------ | M O T O R O L A B . V .

The harmonics of VCO2 and VCO1 interfere and cause some phaseshift effect which should be reduced by adjusting this control just a little bit. The settings of HP-peak and LP-peak are also critical. They should be adjusted so that the filters are very close to (but not) self-oscillation. It would be fun to see some more patches for the ms-20.

(This is a normal delayed vibrato patching.) REMARK: Most important is that the pitch control of VCO2 is adjusted so that the distortion is minimized. The harmonics of VCO2 and VCO1 interfere and cause some phaseshift effect which should be reduced by adjusting this control just a little bit. The settings of HP-peak and LP-peak are also critical. They should be adjusted so that the filters are very close to (but not) self-oscillation. / Mikael Hillborg, Computer Sciencestudent at __ __ _ | \ / / \ | | __ | \_ | |/ \ | \ |__/ \__/ \__ \_/ Department of Computer Systems, University of Uppsala, Sweden email: mikhil@student.docs.uu.se phone: +46 18 46 28 30
