Anyone built Morocco Dave's Master clock with midi?

VendingModular — Sun, 23 Apr 2023 10:29:15 -0700

This week i have breadboarded it because I was unsure it would work. The breadboard version worked like a charm. All functions work. For the libraries I used the first results after googling them. Clickencoder.h has a readme that says to put

High resolution encodersBear in mind that I'm not as electro

Sven — Tue, 01 Nov 2022 13:23:41 -0700

. I would like an encoder to go from, say, 0 to 65535 (16 bits) instead, on a full turn.

Hi,

I think this would be useless. Lets say a full turn is 360 degrees. Divide it by 65535 and think about how you want to set the encoder to for example ...

where can you buy pre-built keybeds/synth parts

floating-water — Thu, 04 Feb 2021 11:15:51 -0700

Is there any manufacturer from which you can buy keybed parts for synths, say, a 25-key keyboard skeleton with the circuit board/outputs for the scan matrix required for it so you can build around it. Instead of having to source old toy keyboards or m ...

do you get some kind of error message or does it just try to upload and then nothing happens and it keeps stuck on uploading ?
I've had that before but I think my solution was just to switch from windows to linux or the other way around. I guess tha ...

How to make on/off switch for audio signal using piezo

PHOBoS — Mon, 09 Nov 2020 15:35:19 -0700

:welcome: :partyguy:

In theory that should work however you might get some bleedthrough even when the lowpass gate is 'closed'.
A low pass gate is nice though as it is less likely to result in clicks when unmuting which can happen with an

As always you did not dissapoint. Amazing build and well documented!
nice detail with the LEDs illuminating the controlpanel.

simple FSR schematics ?

The Peasant — Tue, 21 Jan 2020 13:18:57 -0700

There are a couple of different FSR circuits on this page that work very well:

Below is a bare bones basic circuit that outputs 0 - 5 volts.

Take care,

Ah, thanks for those links! I had come across the Appendage earlier, but got lost in the original thread and decided I was wanting to do something simpler -- but reading through the "Appendage Exposed" document explains a lot that I was groping towar ...

this was during my research . have moved well beyond this now. using beatstep for my Roland voices. ended up strip boarding trig conditioners for most because the beatstep trigs aren't quite crisp enough and would double trig and other things, all ful ...

CV to MIDI preferably DIY

cslammy — Thu, 09 May 2019 18:33:37 -0700

I hate advocating "don't it Yourself", but....I've been considering building the same thing (from quick reading it looks not too terribly hard with Arduino, especially if you can hard code midi channels and CC output #'s and leave out CV V/oct to MIDI ...

Help for a sensor to CV interface

Grumble — Fri, 01 Feb 2019 08:45:56 -0700

but i think that an range of 20cm to 150 cm will make it a bit odd to tame it's behaviour and Output.
There is also a 10-80cm type sensor

Hey guys, hope this is the right place for this post.

So I should start out by saying I have literally zero experience with any kind of electronics, beyond turning things on and using them. So that said I have fallen for Xfer's serum its been my m ...

Oh wow, you are so right about the inverting configuration (forehead slap) I can’t believe I missed that. Thank you! And you’re totally right about the 10k series resistor.

Btw, I opted for the non-inverting config because it has minimum gain o ...

HELP - baby 8 sequencer

electrotech — Fri, 09 Jun 2017 02:12:27 -0700

I agree with 'Grumble' about the value of the pots.
Also, the schematic diagram doesn't show any decoupling capacitors across the supply rails to each '555.
These are essential with bipolar '555s to ensure that the circuit works as intended.
I'd us ...
