i wound like to thx paul for helping me out with the tigger for the freebass ( i love this guy and not in a gay way:D) I have some ideas on how i maybe able to get it going again but will be very basic so input here would help me, if its negative thats cool will save me time .
Any way ok lets start..
i found my old MidI projects book about 26 years old but has a Midi to cv convert its very basic with 3 knobs and a rotary switch to select the midi channel its main Ic is using a 6402 uart chip which i have as this was the main ic for most of the projects in the book i guess i will maybe have to payout 15 pounds on cases as i have 95% of parts ..
please be understanding i just about know how to wire a plug up
here some pictures of boards and layouts.. ok here the power board first
here the main board
Midi input is pin 1 and pin 2 of CNY17(IC1) Sk2 out is pin 13 4013BE (IC5)
Second board
ok this design is a midi to cv converter which is Logarithmic type will this work?? more info to come i am going to do a wiring schematic of the unit but with pots wire and all boards connected it be a image but i need to go to sleep first..
