Arduino Sequencer v1.7 Released!

Ok, Drum Mode has been tested, and seems to work correctly, so it’s time to unleash the latest version of the code to the world!

The only hardware change from v1.6 is to add a SPDT (or DPDT, and ignore one pole) on-off switch, with one leg going to 5V, one going to ground, and the center leg going to pin 4 (you can use something else, but you’ll need to change the code…)

Download the code here: sequencer_1_7.pde

Press The Button Podcast for October 15, 2008

For lack of any better explanation, it involved things, stuff, stuff on your things, and things on your stuff.

Coming soon – Arduino Sequencer 1.7?

Since I had a need for a primitive drum trigger sequencer (for the thing), I decided to hack it into the Arduino Sequencer as a new mode – Drum mode. When in drum mode, the “CV” and Gate outputs become Drum1 and Drum2. Voice selection in the sequencer is handled by note value (0-1023) – 0 is no output, 1-512 is Drum1, 513-1022 is Drum2, and 1023 is both voices (values are subject to change in the future).

I’ve made the hardware addition (as well as some of the soldering for the eventual start/stop button), and have a rough version of the code written, but haven’t actually tested it yet. Once it’s tested and working properly, I’ll have a proper release post, but figured I’d let people in on the fact it’s coming.

In the meantime, I’m looking forward to the ADV-BASS/SoundLab Snare combinations I’ll be programming ;-)

Of course, the ADV-BASS isn’t quite working right. It works well enough for a basic kick, but I couldn’t get it to do all the nutty Syndrum sweeps that I had it doing back in 1998/1999. Will require more investigation.

Progress report

Gear used so far:

  • Sound Lab Mini-Synth
  • Lunetta modular cigarbox synth
  • Arduino Sequencer
  • Midwest Analog Products ADV-BASS (my first foray into Synth-DIY, back in 1998(!))
  • Vectronics Regenerative Shortwave receiver

Gear built in the past week, likely to be used:

  • Ken Stone’s CGS Real Ring Modulator
  • a quick&dirty microphone preamp (that needs more gain!)

Progress:

  • 1 long song – three of four available tracks, used.
  • 1 short song – one track used.

Gear yet to be used;

  • LM567 modulator
  • WSG filter
  • Theremax

So far, so good.

Some hints

Known things:

  • It will be a recording
  • There will be a physical product.
  • All gear used will either have been built, modified, and/or repaired by me (except the recording media itself, and maybe a microphone or two)
  • No computers (except microcontrollers) will be used until mixdown. Maybe not even then.

Unknown things:

  • #tracks: 4? 6? I dunno. I’m shooting for 30 minutes, but could go over. If I go over/under, leftovers will probably end up online in an Opentape, or on NEOelectro.
  • Catalog number? Unclear.
  • Art (any volunteers? You’d obviously get let in on some secrets and stuff…)

Any questions?
