All about music synthesizers in and around my place.
When starting with the TTSH build last year I prepared the Formant power supply, that I still had from the past, as kind of standalone unit. Meanwhile I realized that this would be a little too big to easily fit into the TTSH case I've built. I decided now to …

After a longer break, summer and autumn have passed, I picked up the work on my TTSH again. The TTSH is working, but not ready yet. Of course I still need to build a case for it.
