KiCad in 5 minutes: Designing an SMD PCB for my $30 chord sequencer + firmware updates

video upload by Floyd Steinberg

"I finally learned KiCad and with the help of PCB Way https://www.pcbway.com/activity/anniv... or https://pcbway.com/g/4nkLCf , I created an SMD PCB for my $30 chord sequencer, and I added all the features you asked for after the last video on this project. Table of contents:

00:00 short demo
00:07 hello, what's this?
00:58 KiCad design quick walkthough
05:04 a parcel from PCB Way!
06:36 creating some JST adapter cables
07:04 my thoughts on the whole process, and some advice (read those spec sheets!)
08:36 Quick overview: Analyzing chords and using suggested chords
09:43 chord complexity selection
10:05 passing chords
10:43 santanic chords
11:34 rolling chords
12:07 reacting to velocity
12:29 bass: root note
12:44 bass: key root note
13:04 swipe menus
13:23 sending CC data with the ring
14:04 arpeggiator
14:48 user arpeggiator patterns
16:08 chord sequencer + auto chord progression
17:07 multitimbral multitrack demo (Montage M)
17:57 conclusion and where to get

"I built a nifty little MIDI device that might help you find some interesting new chord progressions. This runs on a 1.28" CrowPanel by ELECROW ( https://tidd.ly/49pImPW , or the new 1.46" version https://tidd.ly/4u51ZEi ) for roughly $30. Table of contents:

00:00 hi, what's this? + quick demo
00:40 sponsored by ELECROW
01:05 hardware needed
02:01 Yes, I came up with the firmware, but that's not important here
02:44 you'll need an external sound source #synthesizer and set it to local mode
03:15 you can play on the device itself or on a midi keyboard
03:28 basic usage
03:49 emotional chords!
04:41 ... or not
05:05 chord analyzer
05:52 passing chords
06:33 bass (chord root + key root)
07:23 this channel needs you support
07:48 trigger key changes (some music theory)
09:15 functional chords, related keys and chromatic/altered chords
09:53 chord sequencer
10:44 flip the screen
11:13 disarm the passing chord function
11:19 some interesting details (automatic voicing, slightly random velocity and more)
12:19 playing "chord melodies" and throwing some "emotional chords" in (proof of practicability)
12:45 using the device to create chord progressions in other sequencers
13:02 a short improvisation (left hand: chord machine, right hand: keyboard)
14:16 conclusion, and some more ideas (and why I need your help)"
