seriously, if you don't plan on selling synthesizers like this, than sell the blueprints to a larger company, or something. this is an extremely nice synth. this seems much better than so much hardware being released right now!
@ryanquist1 Thanks! - I'm working on a module version of the synth which will cut down on production time and costs, which is important as this is all done in my spare time. I'll see how the module sells, then take another look at the construction of the keyboard version. I'm guessing that manufacturers keep an eye on the DIY community anyway and take inspiration from these ideas as they see fit, hence the Monotron/tribe.
Where did you get those keys? I am planning to build a PICsynth and I cant find any keys. Probably 3 octaves or 4 octaves. Did you take them from an organ or other keyboard? I really liked this video! Keep up the great work! I like those homemade synths.
@Synthdude13 Thanks! The key are from an old Yamaha PSR keyboard. I couldn't find 3 octaves cheap enough secondhand so went for 4, which is good as you don't need to keep reaching for the octace selector. Good luck with your synth :)
@SynthStuff Okay thank you! I live near a second hand shop and there is an another second hand shop in our town. Maybe a cheap casio with full keys, that was one of my options. I will separate the keys from the keyboard. I'm planning to build after my final exams of high school.
@Synthdude13 Ok, nice one. Once you've detached the keys from the main circuit board, you'll need to work out which pair of wires in the matrix corresponds to which note, then build a key scanning circuit to detect which key is being pressed - a PIC is ideal for this job. Hope it goes well.
@SynthStuff Looool you said you've used a Yamaha PSR keyboard. I've bought one too! A PSR-15 with 4 octaves. I'm going to give it a vintage look with knobs like the ones on a minimoog. (microkorg has those knobs too if you know what I mean.)
@SynthStuff wow how coincidental I'm planning on making a keyboard and I got my keys from a psr 21 what model did you get yours from? also how do you make the connection between the keys and the components, thanks
@modgemtb Hi, the keyboard in the psr will use a matrix scanning circuit to detect which key is being pressed. The circuit board directly underneath the keys is the matrix - each key is a switch in the matrix. This board is connected to the main board with a ribbon cable with each wire in this cable being either a column or a row of the matrix. The circuit on the main board will send a pulse out to each column in turn, and read the state of each row while column is 'on'.
@modgemtb ...The MFOS site has an example of a keyboard scanning circuit, or you could go down the PIC programming route and set up a microcontroller to do the job and output a CV or whatever. Not sure if it's possible to use the existing scanning circuit in the psr, as this probably produces the sound as well, but if it's a circuit bending project then that may be an option.
@xesionprince There is embedded code in the microcontrollers - the dsPIC30F for the oscillators and waveshaping, and smaller PICs for LFOs and envelopes. The VCFs and VCA are analog.
this is one of the best synths i have ever heard and i have heard a lot of them. i mean if you went into business selling these you would sell a lot of them. its hands down what is missing from every major synth makers product lines today. this is amazingly cool man. kudos to you.
I think it would be quite a risk if I were to make even just a few of these and try to sell them at a price reflecting the materials and time involved. I don't know if people would pay £2000 to £3000 for a homemade monosynth.
I'm working on a midi module version however, which will have less modulation routings but more wave shaping features. And still one knob per parameter - not menu driven. Watch this space :)
@SynthStuff its hard to say who will pay for what these days. i mean people will pay that kind of money for a twenty five year old jupiter8:) your synth has everything i think is missing from what is being offered for sale right now. its really unique and different sounding. it sounds really great. cool you are doing a module as well. very very cool man.
Fantastic , awesome and incredible!!

Is this totally hardware based or is there any software inside? Any microcode?
