Hi everyone ! It is my first post on this forum, though I have been looking at projects people were doing and it is amazing ! I have experience DIY modules for analog synths. Now I got intrested in MIDI, particularly because you can store patches. Obviously on Analog Systems it is imposible (though there are some mechanical-electrical mechanism that can store limited number of patches) I have a plan to build analog Filter Bank, similar to Sherman FilterBank (sherman filterbank is able to receive and send MIDI information, therefore you can store patches). That is the filter I want to build: http://www.oakleysound.com/filtrex.htm. Also I would like unit to have internal patch memory and small LCD screen where I would be able to choose my own patches. What are my options to build something similar ? Thanks !
