New Projects...
Hi Everyone!
I have 3 new projects to announce. First, I have prototype PCBs for the Duo-Phonic keyboard. I've got an idea how to modify a Fatar keybed to use reed switches and magnets as a buss keyboard. I'll post my results.
Second, I'm working on the Microcon. It will be a module suitable for Eurorack or standalone. In standalone, you will need to add a +/- 12 volt supply. I've got the schematic mostly captured. I'm thinking I can get PCBs in about 2 months.
Third, Tom Carpenter at Analogue Solutions is selling Red Square PCBs and panels. Pretty bare bones, but I'm putting a page together to help out those who are building it. There are some unique semiconductors and the BOM lacks some part numbers, eg: pots with switch. Anyway, I also bought an assembled Red Square and will take some photos of the inside so the PCB interconnection and other details will be more clear."
Update via electro-music.com: "To compliment the Steiner Synthasystem resurrection I completed (see here http://www.xmission.com/~dingebre/Synthasystem.html), I'm now undertaking the Steiner Microcon. I'll put up a page with build/calibration notes and will have PCBs for sale. Be aware, it does use two Vactrols which are becoming extinct. They are the VTL5C3/2 variety right now available at Allied Electronics. It also makes use of 5 74C14 Hex Inverters. There are some substitutes which I'll have in the build notes. It also uses a 2n5246 JFET which also recently went away, but it isn't really special and there are substitutes. Everything else should be relatively easy to find.
There are a couple of trimmers on the PCB which will be configured so you can make it a panel pot, like resonance, and sustain level. So, stay tuned.
The Microcon was a standalone synthesizer voice, VCO, LFO, VCF, EG (driving a VCA). It also had a unique way to "fatten" the VCO sound. Below is a photo taken of one Nyle mounted in a custom rack of 8 (or was it 9) Microcons as a special order."
