Spin Semiconductor

I'll continue to hang out at diystompboxes.com, but I'm also developing a more centralized site for my DSP interests which eventually will include some plugin development (VST/AU). Recently I have put together some videos and articles showing how to get started with SpinCAD Designer and develop some...

Hi Frank, I've got the hood up again on SpinCAD and thought I would add license and source info for all the bits in there which have been lifted from this site. The idea being to both include those in the source code as well as generated Spin ASM. There is a thread from about 2016 asking about the s...

Anyone with questions about SpinCAD, please visit the DSP section at diystompboxes.com.

At the moment I have updated my development system and have fixed a couple bugs, for the first time in 4 years, so now's a good time.

I spend more time in the DSP section of diystompboxes.com than I do over here, so to the extent that I'm going to support SpinCAD, that's the place to ask. Of course, SpinCAD just creates SpinASM, so you should be able to get some level of answers here by just posting your code here. I haven't even ...

Few things worth mentioning. a) I offer ad-hoc support (that is, if I see your question, I'll try to answer it) for SpinCAD issues over at the diystompboxes forum in the DSP area. b) People will always be better able to help you if you include code. c) I went and found the "spincadbuilder"...

I almost always have to post to a public forum before finding things like that.

For reference, I have volunteered to answer ongoing questions about the use of SpinCAD over in the DSP section of diystompboxes.com. At the moment, now that I look at it and dig deep into the recesses of my memory, the values shown for "Attack" and "Release" are actually the corn...

this works well and i do get longer reverb, but i get this tones, some kind of metallic sound when i do that, the moment i disconnect the second feedback (not the shimmer feedback) the tones are gone but i dont get longer reverb. Welcome to reverb design 101! You'll notice throughout the Spin rever...

There should be at least one stereo reverb in SpinCAD (two outputs on the bottom of the block). All the reverb code in SpinCAD is taken from the Spin programs, either "Free DSP" or this forum, or the OEM projects code samples. Only the "small reverb" IIRC is small enough to have ...

Cool, I used to work with Perry Cook and sold him a mandolin.

Are you suggesting to randomize the frequency of the S/H using it's own output? I hope the universe will not collapse. :D Yes, that's what I'm proposing. I'm sure there is some theoretical stability consideration but it is beyond me. I'm pretty sure I did this at one time. I also realized it only s...

I would (using SpinCAD, of course) set up a noise generator going into a S/H. This generates your typical random step waveform. Next you'd want to filter that using a low pass and scale the output to feed to the LFO input of the S/H, so it's not at a constant frequency. Highpass filter the S/H wavef...

Interesting... a) I don't think my hearing is all that great b) I prefer slower modulation speeds c) I don't spend a lot of time with the FV-1 The concept of what you are doing is the same, it is a 1st order Lagrange interpolation AFAIK, with better resolution to support quickly changing delay times...

I presume you've seen this: http://www.spinsemi.com/knowledge_base/coding_examples.html#Servo_technique http://www.spinsemi.com/knowledge_base/effects.html#Continuously_varying_delays Your question seems to mix two issues. a) Can I use an arbitrary waveform? answer: yes, see above b) Can I get more ...

That code looks suspiciously like it was generated by SpinCAD. Normally if you are using Spin ASM and using memory buffers, you will reference relative to the memory buffer, for example at the end, or in the middle (I forget the exact syntax). Or, the beginning of the buffer + 1, or 10, or whatever ...
