Looking for DIY drum recommendations - ideally desktop
[...]
Suggestions please.

DrumKid.
https://mattbradshawdesign.com/projects/drumkid/

It's available as a ready-to-use machine and as a DIY kit.

I don't have much height reserve though, since I gave mine an acrylic front cover plate limiting the free space 01IMGP3717.jpg Cutting and drilling that plastic material is definitely not my favorite pastime :roll: , and it will never be. The Opera Rotas just sits in the black wooden stand I made, ...

That's what I'm referring to as hardware patching. That part is not hard to do. As I proposed, a small adapter and some hardware patching would be needed to re-assign pins and some of the output circuitry, but I guess it should be manageable using a small protoboard. Ah, OK, thanks! I had assumed t...

If I'm not mistaken (I may very well be) it could be feasible to replace the 4n35 with the more commonly used 6n137 optocoupler. This would of course take some hardware patching, but it would not have to be a completely separate board (more of an adapter), right? Sounds tempting, but I don't think ...

The one I really don't understand is using mF for "microfarad"... I don't think I've ever seen that in an actual schematic - and it would simply be wrong (and yes, I am aware that you are aware of that ;)). mF is milliFarad, not microFarad. Electrolytic caps in the mF range do exist, although they ...

<quote>Ontop of stopping the sequencer, another nice to have would be a way to clear the pattern</quote> This and mute/unmute channels are quite asked and will be in the next code iteration. The analog clock in seems that will work too, fingers crossed That. Sounds. Awesome! :tu: :tu: :tu: The prob...

And - ability to sync to an external clock provided - a mute function (as, for instance, in the Beatstep Pro) so it stays synced while not putting out sound.

When I have the new MIDI firmware I will try to implement "analog clock in" in the current MIDI IN port. I guess should be doable without hacking the hardware side

That would be awesome! And a big thank you for your efforts also from my side!

In the meantime, if somebody has any idea: maybe bypassing the optocoupler and conecting the midi cable directly to the microcontroller doing some 5v>3.3v voltage division? or something like? Perhaps something like bypassing the optocoupler and using a small external interface box based on an 6N137...

well.. this is what I am looking for.. anyone bought from them and shipped to EU? Well yes, I did :D. Somewhen in spring. I have no much experience with custom fees; I only know last year they charged me 30 euro for a small package coming from Canada to Italy! I'm not sure in how far this is compar...

If I want to use an LFO (through an attenuator/EG) to create a pitch tremolo, how would I do it? Do I need to combine the pitch CV and the tremolo CV in a mixer, Before going into 1v/oct? That's one way, yes. Or am I missing some other obvious method? Many oscillators have several CV inputs (typica...

I'd like to add two duet albums -

Harald Grosskopf & Axel Manrico Heilhecker - Are you psyched?
Mani Neumeier & Zeus B. Held - The secret lives

Both are recent, as in: they were released in the second half of 2020.

I love both of them.
(Both are available through Bandcamp, btw.)

Kodamo EssenceFM

Edit - tron23 beat me to it by a few seconds

They're not in Europe, but PedalPCB (pedalpcb.com) has some nice PT2399 based delays.

I built four (!) of them earlier this year (Spirit Box; Dark Rift; Magnetron; Seabed), and they all sound great and different.

Wow, so many cool ideas! I really appreciate each and every contribution to this thread, thanks :tu:! Especially @kdjupdal: Yeah, I had briefly thought about noise into s&h as well. But didn't explore this further (thus not getting to the comparator part ;)) when I decided to order the MI Branches P...

I'm not sure two small IC sockets will work the same as a large one. They have a small edge around them. Using two small ones could result in the edge obstructing full insertion of the IC. I would check that first. From personal experience (yes, I actually did do that once or twice - was out of DIL...

Also the Yusynth Random Gates is fun!

Thanks, that looks interesting, too . At first I thought it's probably similar to the MFOS one (which I already have as part of the Noise Cornucopia module), but the latter is truly random and doesn't have a clock in.

there are a few ways this could be done with logic if you want. if the incoming gates clocked a shift register noise source, and then the output of the shift register was AND'd with the input, youd get a gate output with 50% probability. otherwise you could go with a clock generator with variable p...

I guess its done digitally I was thinking "perhaps something with logic gates", but that didn't get me too far (yet?)... I guess its done digitally, but maybe have a look at (half a) Mutables Branches for some ideas...? Thanks, I'll have a look at that! Edit: Yep, that looks good indeed! And now I ...

Hi, I'm looking for a gate randomizer circuit. I don't mean 'random gates' here, as for instance included in the MFOS Noise Cornucopia, but rather a circuit that accepts a gate signal and randomly decides if it may pass or will be muted, preferably even with a "probability pot". Something like this:...

Why is that? You learn a lot, the "I have built this myself!" feeling when it works is great, you have your own unique instrument that no one else has. I also built several guitars, btw ;). DIY isn't necessarily cheaper than buying a complete instrument (have a look at my signature line below... 8-...

Maybe they licensed it from arturia...

I know from a 100 % reliable first hand source (German Arturia distributor) that this is not the case.

There's lots of sellers on platforms such as Ebay. According to my personal experience, some are particularly good for pots, others for ICs, etc.

instead of replacing the ones i put in, can i ADD another of the same value capacitor to it by just soldering it into the holes as well as the one that's already there.

Sure. Their capacities will simply add. So if you have 1 µF and want 2 µF, put in another 1 µF in parallel.

I wonder if as the thing warms up a cold solder joint that works on start up get progressively worse as it warms up? Imho, yes. I experienced a similar behavior after I had finished it about 2 years and two months (or so) ago. The first time I then used it during a jam session with a friend, one of...
