few recordings
Here's few recordings of my no input mixer .On the images among the pedals also a Universe Reverb pedal i bought from AliExpress . I said i never use it ,it's not getting along with rest of my diy gear ... but in the latest recordings i just add a little tail from it .After all this time in building gear i like to use mostly my homemade gear for recordings .

Mixer
Finally i completed this diy mixer ,it's not as pretty as some other things i've done ,but i changed my mind too many times about too many things while building this ,so in the end i only waned to complete it and it's done . This is a Buchla 106 Mixer ,with 3 x SIAM (Siemens based EQ) on 3 channels on one of the two groups of the 106 Mixer .There is mute on all channels and 4 groups of aux channels based on early Serge Mixer using 741 ,i expanded the 106 to 4 channels for group or 8 in total ,so that extra channel at group is actually two channel summer meant to be used as return for 2 aux groups , those 2 extra channels have Tape Saturator Colour MK1 which can be bypassed with high pass switchable from 40hz to 60hz .The second group of the mixer has no equalizer . In addition there is 4 channel input joystick that works as a four channel panner ,or two x two channel panners ,it can be useful to browse thru the 4 aux groups ,the joystick has Colorupter Optical Disrupter Colour that can be bypassed .This build was not easy cause i reused lot of materials for the panels and the enclosure ,the enclosure is leftover from machines in an old textile factory ,the inputs and outputs are in the back of the enclosure and that part is fitted additionally but it turned out beautiful.

Synthesizer Secrets
https://synthesizerunderconstruction.blogspot.com
I made a new Blog Page ,is this end of life for this one . Over the years i made more then few PCB layouts ,and many of them were built ,tested ,modified ,so it kind of itches to place them in one directory ,like a schematics vault ,or a modular synthesizer ,so i found a layout that is working good for this purpose ,this documentation is free to download along with gerber files . Music and pretty pictures are not hosted here but i hope the list of modules will grow as i need to revisit some of the earlier layouts i made . Most people will just go and buy the kit and this is if you think you might save a few bucks . Here's the link :
