stm32 is still available in smash tv's shop. It is still a very valid platform, and is the core that is reccomended in SEQv4 (the full featured version) You should start with an "official" midibox project like seqv4lite since it is well documented and many users in the community can help you with troubleshooting.

The AOUT LC will be fine to control the filter, but if you want to have CV control of VCO pitch, You're going to be much happier with the AOUT NG And Yes, You need to use bipolar power supply

Do you have TK's permission to sell this? If so, I might like to buy it from you. What is your price?

Thanks for the input! I tried just playing a really long note, but the pitch didn't change until the next note.

Thanks for responding. I'm not aware of an envelope function in MBSEQ

Is there a way to do this?

The problem is that the MBSEQv4 midi is working at 3.3v instead of 5v like MOST midi instruments require. You need to build a 5v level shifter. You can find schematic for this circuit on the MBSEQ hardware page it's called "LPC17 output buffers"

Hello, I have read the section of the seqv4 manual which describes different functions within the LFO menu but it is still unclear to me how to use the LFO to generate a smooth and consistent CV. If I set the LFO to "note" it modulates the CV channel I have assigned, but it seems to only work on an active step, giving me stepped or quantized CV rather than a smooth and continuous CV. All I'm trying to do is modulate the cutoff of my filters like the way a traditional LFO module would. What settings should I use? Ideally I would like for the LFO to continue running and just retrigger the cycle with active steps...

I switched to a different cable (also 6' long) and it is now working perfectly! I suppose the quality of the cable can be just as important as length!

OK, I am using a 6ft. long printer cable as you have for your Aout module. I will try one that is 3ft. and report back

The 2.8v you are referring to is the limit when AOUT is in Bi-Polar mode correct? If so, I don't think this applies, I am using Unipolar which goes from 0v to 10.67v for the full tuning range. I have not experimented with bi-polar mode, so I cannot answer your question. Can you take a look at this project page for the YUSYNTH VCO to confirm that the AOUT should indeed be used in unipolar mode to control pitch CV at the V/oct input? here: http://yusynth.net/Modular/index_en.html navigate to VCO

I don't think the YUSYNTH VCO uses bi-polar, A1 is the note that should be played at 0v. I can't imagine why anyone would want to play a note lower than this...

BTW - I really like the quality of smash tv's stuff!

Hello. I have built Aout NG this weekend. I have noticed that It ocassionally puts out incorrect voltages. For Example, I can play the default pattern (just four quarter notes of C3) and it will actually trigger a different note/voltage randomly sometimes. This is not just the sequencer, I have the problem when playing live from midi keyboard also, I can kit the same key multiple times and sometimes get a different note... for more information I am running seqv4 on LPC17 to drive a YUSYNTH VCO 1v/oct. AOUT NG is configured in unipolar. Under CV options, in the calibration I get 1v to measure 1v, 2v measures 2.33v, 4v = 4v, and 8v = 8v, also MAX = 10.67v Is the non-linearity around 2v something to be concerned with or is this normal? What is the reason for random notes?

I wish lumenlabs was still around, they had one with a 19"x19" cutting deck for under a thousand... I really don't like the idea of a CNC router that uses wood for the frame. I think extruded aluminum (like 80/20) would be much more accurate and long-lasting

Maybe these settings are saved per session on the SD card?

I just got my MIDIIIC4 from smash, I'll probably order a new back panel to accomodate it and I'll update this in the cut file after I order and confirm athe fit.

They have a country of origin stamp on the back, so someone went to great lengths to remark them if they're not genuine.

you'll need to use bipolar for your ssm filters

The case is lasercut acrylic from ponoko. If you have the file you can order it from ponoko.com

Don't forget to supply the 6581's with 12v (instead of 9v like your 6582's) and use the correct capacitor values, I think 470pf? for the 6581's filter. Also upload the firmware for 6581 so that the filter is calibrated properly.

This issue is known as the adsr bug, it is a problem with all SID chips, and if you've heard a demo that did not have this sound, a noise gate is probably applied to the recording. The only real solution is to use an external ADSR and VCA. It's actually considered to be a characteristic of the SID sound that most CHIPTUNE musician's have some sort of nostalgia for.

this thing looks awesome! What touchpanel are you using?

I think 64 encoders is a limitation that is proportional to the number of shift registers allowed. You can hook at least 8 lcd's though
