Turning a Fixed Filter Bank Into a Modulated Filter
JH posted the following to AH. He gave me the ok to put it up here. Title link takes you to a 7M WAV. Enjoy.
"I've just finished an experiment of using two Frequency Shifters to turn a Fixed Filter Bank into something animated, modulated.
A drone sound from the OB-8 is sent to a first Frequency Shifter, which shifts the audio signal up by a variable amount of Hz.
This upshifted signal is sent thru a filter bank (MAM vocoder, with a rather thin-sounding setting with all even channels up and all odd channels down.
This filtered signal is shifted back down with a second Frequency Shifter, by the same amount of Hz that the original signal was shifted up.
First you hear the very thin sounding unshifted signal - just the OB-8 drone processd by the vocoder filter bank.
Then we start to modulate the Frequency Shifter with the Joystick.
link ( 7 MByte - I tried mp3, but it was no good)
Please note that there is no filter modulation! The filter is fixed all the time (static formant filter) - it's the signal that is modulated!
Sorry for the rather low quality of the unmodulated sound - I just made this experiment at 1 am after finishing the hardware. :)
Background about this project: link
Let me know if you have ideas what else could be processed with this. I'll certainly try reverb, and all kinds of fixed filters.
JH."

What is this?
Ross sent me the following:
"I recorded these 2 tracks off the radio in the mid 80s, and have no idea who it is...can you pass on this web address to see if anyone can help me solve the 25 year puzzle?"
After listening to them I'm actually curious myself. If you know please post in the comments.

Update on the Stolen Buchla
Previous post. More details:
"You may have heard, but the College's beautiful Easel was stolen sometime around the 29th or 30th of June from it's studio. This instrument had etching and a steel label fixed to the power-supply cover. It was stolen without it's cover.
We are looking into a suspicious person who showed up to take my summer class. A Ben Katz from California, who claimed to have a Roland 100 and an AKS from 'estate sales' was here for the week, and disappeared the same day as the Easel. We have the campus police seeking him. If you have any information or hear of any easels on the market, it may be ours. If anyone knows of this person, please forward information to me or campus police 360 867 6832 atten Pam Garland garlandp (at) evergreen.edu
Please distribute this information to any and all possible places to help us recover this instrument. I have been teaching with it for nearly 30 years, and cannot believe it has been stolen."

WMS 1020A Analog Sequencer
Title link takes you to more shots pulled from this auction. "1970s vintage WMS model 1020A analog sequencer, serial #D10218, and accompanying power module #100-D. This unit is in very nice to excellent used cosmetic condition and 100% fully functional plug-and-play condition. All jacks on the unit are 1/4" and it runs on 117V US voltage. WMS (i.e. Wasatch Music Systems) was a very small 1970s US company and I believe they were based out of Utah.
This unit is so incredibly rare that I haven't ever seen another for sale, though I'm guessing they made at least 17 others... my logic being that the serial numbers likely started at 1020x (due to 1020 being the model number). It's very cool and very flexible. It has many of the features of the great Arp Sequencer like random mode, a voltage controlled clock that can be normalled to the second voltage row and individual outputs for each row with parallel and serial mode. Serial mode is particularly cool on this one because the A/B outputs both flipflop at the end of the row (with LEDs!) so both outputs functionally serially and opposite each other. Though it is missing a couple of important features of the Arp (quantizer and gate busses) it has a few bonuses of its own, like the negative voltage outputs, switchable V-trig / S-trig gate output to drive pretty much any kind or brand of synth with cv/gate inputs, and of course 2 extra steps per row. And it is much smaller than the Arp Sequencer. All jacks are 1/4" and the "Carry" output is a reset trigger output so you can use it to restart your other sequencers in your setup. Other functions should be fairly self-explanatory if you've used analog sequencers before. One thing that's a little weird at first is that both voltage rows are at zero when they the knob marker is on the line... this means that zero for Row A is at 6 o'clock while zero on Row B is at 12 o'clock. Oh, and check out the killer fake wood (plastic) end cheeks with relief WMS logo on them!"
PAiA Fatman Plus
This one in via Brian Comnes. More pics here.
Update via Steve in the comments:
"Hey, that's mine. You should see the original which that was rebuilt from. A nice, rusty metal box, but it all was unlabeled and it didn't actually work."
http://www.nuxx.net
Another update via Steve:
"Sorry, took me a bit to reply. I just added a switch to sync the VCOs, the subharmonic generator(s), the new case, and a couple of other things. I figured that made it a 'Plus' to the current synth. I wanted to keep the original name since it's still very clearly a FatMan, but I wanted to differentiate it somehow.

"The following link is a soundbyte of an all-Plan B patch, which along with a
single Model 10, 13 and 15, incorporates three modules you've not seen nor
heard before...but you will real real soon. That's all I'm going to say.
OK OK OK, one more thing: that ain't the Model 12 filter you're hearing.

Zena SoundScape Project
Title link takes you there. Via David:"I've been a regular matrixsynth blog reader since I first put my hands
on a little blue novation laptop module ... now I recorded a few demo
tracks, and it would be a great honor for to be worth a post on your
blog
The music is Ambient, and not nova only : I also used some an
Andromeda, Wavestation, K2000 and Novation Nova, while all drum
sequences come from laptop based software : recording gear shots are
on the way ...
Mainly a live session, mostly live FXs, slightly cut and reworked ...
of course any comments/advices are welcome :-)"
I like it. ; )
MS-02 Schematic
Title link takes you to the full scan. Here's one in color. Both mirrored here.
Update via the comments: "Hi. Thanks for sharing these schematics. And great job with the transcription. I am implementing the Hz/V-V/Oct circuit, along with a Trigger processor in my Yamaha SY2A mono synth. Works pretty well. Note : I've noticed 2 mistakes in the coloured version of the schematic. If you care to fix it, I think it may help people 'cause they'll probably, as I did, use the coloured version, since it is easier to read.
Trigger Processor :
- IC-9/10, first half : the op amp's input symbols (+ and -) are reversed. "+" should be at pin 3, and "-" at pin 2
- IC-9, sec half : The mistake is also on the original schematic. +supply pin should be 8 instead of 3."
The AM0600
Title link takes you there."The AM0600 The Analog Metropolis version of the Roland CSQ-600 has been extensively re-engineered with the following changes:
The case has been ditched, and the main PCB and PSU integrated into the AM Modular Cabinet.
The CSQ-600 is controlled from a new remote front panel, linked to the sequencer via a ribbon cable.
The remote panel is a standard AM style panel, just 135mm wide. Have a look at the mocked up front panel to see how much we have slimmed down the controls.
Some controls have been left on the CSQ-600 PCB, to simplify the front panel and because they aren't likely to get used much (e.g. gate rewrite and portamento).
The remaining key controls have been located on the new front panel, and replaced with high quality components which transform the usabaility.
A new replacement potentiometer for TEMPO
New toggle switches and buttons
New 5mm LED's, blue, red and aqua green
The original inputs and outputs have also been slimmed down to the bare essentials, and located on the new control panel.
The CSQ-600 will sync to an external 1 beat per note signal. So I have added MIDI clock sync.. "

My Cat Programs Synths
Here is a shot of my cat JD going over some patch sheets for the Sequential Circuits Multi-Trak.BTW, I sent this shot to Cute Overload. If you haven't seen Cute Overload, check it out. It's so cute it'll make you sick. ; ) It's a daily stop for my two year old daughter, so I thought I'd suprise her by trying to get a shot of our cat JD up on the site. Currently he is on Cute Caps where you can vote for captions and submit your own. Feel free to do so yourself. BTW, if you submit any good captions, feel free to post them in the comments of this post.
Go JD! Go!

Magical 8bit Plug - NES
"The best way to get 8-bit sounds is to employ a real NES system or Game Boy for fifteen bucks and go to town — nothing else sounds quite the same. But for the next best thing, and the ability to do evil things to those sounds within a serious host, this free plug-in from Japan that will do the job"Title link takes you to the post on CDM. Here's a link to the official site's download page in Japanese.
