A patch requested by @chemie, who wanted a dub chords patch.

dub chords.axp (80.9 KB)

instructions here: dub chords - patch instructions - Google Docs

connect your USB MIDI controller to the USB host port and play a key. use the encoder to switch scale key. press the encoder to bypass delay and reverb.

I can’t get any sound out using MIDI. I tested the MIDI controller and it works with other patches. Anything I should do once I load this patch?

3

what MIDI keyboard are you using? I’m using iRig Keys

4

or check the filter knob (knob 5)

I spent some time and this is the summary so far:

  1. I am using both AKAI MPK249 and KORG SQ-64. Both produce no sound in this patch. I tried many other patches for control. They seem to be working. I checked Knob 5 too. No sound from 0 to 127. No change at all. ( I tried different velocities too)

  2. If I use the Keyboard within the software it works though!

  3. I can send MIDI from Ableton to the patch, but it doesn’t produce sound. ( I tried different velocities too)

  4. I tried “3” with other patches. There was no problem.

6

I modified an existing patch and came up with this. Can’t wait to try yours.

if you have a korg SQ-64, in the patch change the midi device option in one of the patcher objects from ‘USB host’ to ‘DIN’, and then use your MIDI DIN output on your korg SQ-64. if the midi device option in the patcher object says ‘internal’, don’t change it.

Would that be the same patcher object like in the screenshot above?

What’s going on is, Kelvin is rerouting the incoming MIDI to create a chord when you play only one note. If you want to play it using “regular” notes, like press 3 keys to get a minor chord, the patch needs to be simplified a bit, correct, @ktttttt?

to play the patch regular style (without the chord generator), go to ‘dub echo: sound’ page and turn down ‘3rd level’ (knob 2) and ‘5th level’ (knob 3). that way you’ll get a normal polyphonic synth

Well first of all thanks for all the help. Now I understand patching better. This was very educational! Also great job with this patch!

Here is what I did with Kelvin’s patch very quickly:

Note that I play around with the knobs in real time just to have a better feeling.

As you can also tell, I also changed some filter and envelope settings in the original patch as well as adding more delay. I think more reverb and delay won’t hurt. If you listen to “ambient dub techno”, you will hear these sounds have huge reverb and delays.
