https://diode.zone/videos/watch/1f61309c-3e15-4525-b534-b9ad039376f5 Here's a slight update to my MIDI synced PT-2399 delay from https://diode.zone/w/9Xe4J655RLJfx9uWtyrZLh I replaced the Arduino Uno with a Nano and added an OLED display and one more potentiometer. After a bit of code fiddling the display now shows the (approximate) MIDI clock tempo, as well as the first and second beat of each bar (the latter was a bit of an unintentional accident). Using the new pot I can now choose different echo intervals - triplets, dotted and whole notes. (For the video I removed the dotted notes as these didn't really work with the tripletty demo track) =========================== The project is just a mashup of several tutorials I found online: The most crucial one is "MIDI synchronized echo with PT2399" by DZL: http://blog.dzl.dk/2018/03/20/midi-synchronized-echo-with-pt2399/, The MIDI input circuit is based on the trusty "MIDI for the Arduino" tutorial by the excellent Notes and Volts: https://yewtu.be/GxfHijjn0ZM, Finally, Dud on the LOOK MUM NO COMPUTER forum posted a great list of mods for the module, of which I implemented a bunch: https://lookmumnocomputer.discourse.group/t/cheap-pt2399-reverb-delay-module-diy/801, =========================== These things are still on my wishlist for future versions: A wet and dry output, Stereo delay using a second PT2399 module, Control of the MIDI delay interval via MIDI CC, a tap function when in manual mode Tue, 20 Oct 2026 15:50:08 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://diode.zone https://diode.zone/lazy-static/avatars/61b689b7-84d5-43c7-9fa8-e63a7fd1d952.png https://diode.zone/videos/watch/1f61309c-3e15-4525-b534-b9ad039376f5 All rights reserved, unless otherwise specified in the terms specified at https://diode.zone/about and potential licenses granted by each content's rightholder.
