Spin Semiconductor

there may not be a simple solution to click removal but I just tested one that should be possible in the FV-1. I used the previous time != current time (checking if it changed) to trigger a very short sub 1ms attack/decay envelope controlling the amplitude of the feedback. Im going to try this in FV...

Id be curious to hear an example if you have one you are willing to show. Why not try an open compare/contrast

how do you code RDFXcoeff = 1 - exp(-2*pi * Freq / 32768) in spinASM? Im a bit lost as to how to do complex math and how to use the exp instruction, I don't seem to get anything from it when I ran it on a pot for testing

Hey there! I want to implant them in an 8voices (x3 osc each) semi analog synthesizer I'm working on, and wanna implamant 1Fv-1 for each 2 voices (total of 4 fv-1's) I just don't know how to write the code for it, I found one for 4poles but not for 3/2... Cool, I love analog synths. I run a modular...

I don't understand why people don't give their variables somewhat readable names. its already alien enough working with 3 letter opcodes, can't variable equs just be "frequency" or "freq" or "lowpass" or even "LP" jeesh :P HAHAHAHA did you read the code I post...

those are pretty easy to implement and Im fairly sure you can make one using spinCAD, which is worth checking out and pretty easy to make some nice filters for FV-1 What is your need for them? it this as part of a hardware device DIY thing or are you working on some sort of pedal or product etc? jus...

I am wondering if anyone has tried using a pot input as a 1 volt per octave input for modular synth tuned effects/oscillators? it strikes me this is a decent chip to actually synthesize as well: https://www.instagram.com/p/BG5zU87hyuI/?taken-by=axiomcrux https://www.instagram.com/p/BG2FK-thymG/?take...

nice, I had the same issue and my hack was to compress the folder to a zip on the desktop, and open it from my mac. hahaha

Many thanks for the reply Frank. That makes things simpler. I can provide a zipfile with an example binary for people to use. I'll include the source & a README stating where to get the originals of the source, the authors of the algorithms etc. The module has an OLED display to provide basic d...

There's a very useful block diagram. http://www.earlevel.com/main/2003/03/02/the-digital-state-variable-filter/ rdax wf1, 1 mulx wf rdax wf2, 1.0 wrax wf2, -1.0 rdax adcl, 1.0 wrax temp, 0 rdax wf1, -1 mulx wq rdax temp, 1 wrax hp_out, 1 mulx wf rdax wf1, 1 wrax wf1, 0 A couple questions, how do yo...

Someone gave me that code for the notch function, which I threw into SPinCAD Designer without much thought, but I don't think it is very efficient. I have a more recent two-pole state variable filter that should be able to do LP, BP, HP all at the same time. I'll try to remember to post that this e...

a bit more work, are my labels correct? what would reg0 be? ;------ Resonator equ freq reg1 equ reso reg2 equ input reg3 equ output reg4 RDAX POT0, 0.2 ; frequency pot WRAX freq, 0 ; store frequency and clear RDAX POT1, 0.01 ; resonance pot WRAX reso, 0. ; store reso and clear LDAX output ; load out...

Here is where I got with it: ;------ Resonator equ freq reg2 RDAX POT0, 0.2 ;frequency pot WRAX freq, 0 ;stored in reg2 for frequency RDAX POT1, 0.01 WRAX REG3, 0. ;store reg3 and clear LDAX REG1 ;load reg1 MULX freq ;multiply by freq RDAX REG0, 1. ;ACC+reg0 WRAX REG0, -1 ;write reg0, invert RDAX AD...

there is a skip instruction specifically for zero cross
