How is the progress with the firmware? Honestly stucked. Maybe Im open sourcing it in case any other guy(s) wants to keep developing it Maybe there are some pointers in here for midi over usb. It works for Arduino leonardo boards and is the way it was implemented on the NS1nanosynth might be worth ...

A bluepill polysynth alternative is a great idea!

Lovely. What a brilliant machine. Love it!

Hi aseaman, it appears that your electrolytic capacitors on the OPL2 board are orientated the wrong way around. You will need to desolder them and replace them with the grey negative stripe of both electrolytics facing the right side of the board. The pic above shows how they should be.

Thanks for the last update. Changing the sample rate is now much smoother. Much appreciate your work on this.

What's the current sample rate default ? I've cropped a short bass drum to 200ms..
Thanks again

Thanks that's helpful. Just took a look in Wavelab and the indicators are in 1 millisecond increments. So that should be helpful in creating a drum kit whilst staying within the limits.

What is the maximum total size of the 5 samples that can be uploaded ? Does each sample size need to fall within certain limits ?

A little afternoon jam with the Drumkid/Nord combo. Nice and gentle

Enjoyed listening and watching. Thanks for sharing.

I used a white uni paint marker extra fine. Trick is - if the slots are too narrow for the paint marker tip, be ready with cloth to wipe excess from the top side in one swipe. Normally these narrow tips just fit in the slot if they are unmarked alpha pots. This is just one coat, I will do another fo...

My favourite part of the patch manual - 975-999 Random glitches Each of this patches is different, experimental and weird.

Hi, got one recently. Build quality is good. Wooden parts fit together with just the right tolerance. The 'classic' was what I bought.

I started with 1U foxfield tiles. Then 1U NLC. Then 3U NLC like squid axon and Arseq. I'm happy that I did these before 16n faderbank and currently a ripples with 0603 parts. You develop a confidence for SMD by starting with easier builds I found.

Just thought I would give it a test for the sake of it, a separate controller isn't that important really. One thing i'm tempted to do though is use a little white paint marker on the pots, the pots are great quality but i'm missing my indicators

Yeah clock from circuit working as expected to control tempo of drumkid and sounds great with drums from both units.

The drill holes on the switches are too small but I was able to smash them in with enough pressure. Now I notice that because of the 2mm difference in mounting height, the panel bows when everything is tightened down. I can remove the pot covers but then I need to use polyimide kapton tape. The swi...

Just checked drop turning off sound to left and right and the A B D randomise function, both work so I'm pretty sure the upload worked. Switch is in midi position but still no response from drumkid with 16n as a controller. Haven't tried circuit yet, but in case it's relevant I'm using a 3.5mm to mi...

Ah ok. Maybe I did something wrong then. Tried a novation circuit and 16n faderbank and got no response from drumkid. I didn't upload the 'blink' code to drumkid as a test though so maybe I messed up. The switch was definitely in arduino mode I remember.

Just uploaded 1.1 firmware with no problems. My controller wasn't set up for comms on channel 10, so hopefully when I change that midi cc should work also.

Completed my build yesterday. Works great. Love it!

but I will find time soon(™) to write the new firmware. :miley: You know you want to :mrgreen: :tu: Your words are my commands. A firmware update consisting in: -Cleaned source code and added comments in english -Code optimized to run faster, so the envelopes/LFOs and rungling achieve higher speeds...

You know you want to

I have a DIY quad attenuator and a matrix mixer that both have befaco style micro knobs. I don't like them. They feel awkward to turn compared to others. It's as if theres not enough torque and grip for a pleasant adjustment. I do have mild arthritis in my hands but anyway just my 2p worth. Funnily ...

Heres the Alps datasheet https://www.mouser.co.uk/datasheet/2/15 ... 524911.pdf
It's the same 4mm.
