Creative Programming for Digital Media & Mobile Apps

I’m doing this Coursera course at the moment: Creative Programming for Digital Media & Mobile Apps. Fun stuff! For the 2nd week peer review assignment I made this in Processing. I wrote the music for this, and found the video footage on archive.org. The harder I blow on my instrument, the faster the lady moves. And those circles in the background also respond to breath (bigger for louder).

Groovesizer mk1 Manual

You’ve built a Groovesizer mk1? Awesome! Here are the operating instructions for firmware V0.19.

groovesizer_man

 

Pick-up:  The pots perform a number of different functions. To avoid sudden jumps to new values when the pots are turned, values will only change once the pot has passed through its currently stored value.

TONE CONTROLS

  • pot 1 – grain 1 pitch
  • pot 2 – grain 2 decay
  • pot 3 – grain 1 decay
  • pot 4 – grain 2 pitch

NOTE ENTRY

  • but 1 + pot 1 – 4 – note entry for steps 1 – 4
  • but 2 + pot 1 – 4 – note entry for steps 5 – 8
  • but 3 + pot 1 – 4 – note entry for steps 9 – 12
  • but 4 + pot 1 – 4 – note entry for steps 13 – 16
  • rests – turn the pot all the way anti-clockwise
  • ties – turn the pot all the way clockwise
  • multiple notes can be edited at the same time by holding down more than one button

 CONTROL

  • pattern length – adjust the length of the pattern (1 – 16 steps) with the control pot (no buttons pressed).
  • tempo – adjust the tempo with shift + control.
  • note duration –  adjust the duration of the notes with shift + pot 4.
  • swing – adjust the amount of swing with shift + pot 3.
  • tap tempo / retrigger – retrigger the pattern with shift + but 4. Multiple taps will adjust the tempo.
  • reverse – reverse the playback direction with shift + but 3.
  • transpose up – transpose the pattern up a semitone with shift + but 2.
  • transpose down – transpose the pattern down a semitone with shift + but 1.

PATTERN MODE

  • enter/exit pattern mode  – hold but 1 and press shift (not to be confused with transpose down – see above)
  • bank select – choose a bank from 1 – 8 with the control pot (no buttons pressed)
  • store – press and hold any one of but 1 – 4 until all the leds blink on and off. Press the same button again to store the current pattern to that location, or any button to exit .
  • recall – press but 1 – 4 to recall any pattern saved in that location for that particular bank. By default, the selected pattern starts to play as soon as the end of the current pattern is reached (quantized).
  • immediate recall – to start playback of a selected pattern immediately, hold down shift when selecting the pattern with but 1 – 4.

And that’s it – have fun!

Groovesizer mk1: DIY 16-step sequencer and synth

 

***UPDATE***

This project has evolved substantially – follow developments regarding the Groovesizer DIY kit at groovesizer.com. To distinguish this project from the kit, this one has been rechristened Groovesizer mk1.

I’ve attached a 16-step sequencer to the original Auduino lo-fi synth and have added 8 LEDs and 5 buttons to the original design, and thus the Groovesizer is born. You can download the Arduino sketch here Groovesizer Arduino Sketch (v0.19). And here’s a breadboard schematic:

Groovesizer-mk1_2

You’ll see I’ve maxed out all the ins and outs of the Arduino. I feel I’ve pretty much reached the limit of features I can support with the buttons and knobs available. For a future version, I’ll get into multiplexing to add more buttons, maybe an LCD, and while I’m at it 8 more LEDs.

Here’s the current feature list:
– note entry for individual steps or groups of up to 4 steps at once
– rests & ties
– pattern length from 1 – 16 steps
– pattern retrigger
– tap tempo
– pattern reverse
– pattern transpose (up and down in semitones)
– variable note duration
– swing/shuffle
– MIDI out
PATTERN MODE
– save and recall up to 32 patterns
– trigger patterns quantised (Ableton live style) or immediately

Here’s the link to the MANUAL.

By the way, I wanted to reclaim my Arduino for future projects and make this one permanent, so I replaced the Arduino with a hackduino, following this recipe. It works a treat. I’m considering having Groovesizer PCBs made that incorporates the hackduino. Anyone besides me interested in something like that? Leave a comment.

Latest Firmware:
Groovesizer mk1 – v019 – incorporates DuaneB‘s volatile fix

UPDATE 2 (2013-12-08) – Frontpanel Design

Splendit bend it did a nice demo on his SoundCloud page and also designed this cool frontpanel. Thanks for sharing, Splendid!

Creating Sweeps and Swells with Reason’s Thor Synth [Tutorial]

I’ve been using Reason to create sweeps and swells for my MLO sets, and I thought it would be a good subject for a first tutorial.

I’m using Reason 6.0.2 in the vid, but the Thor synth has been around since Reason 4.

Recording live drums for Suncake Lounge Vol.2

Yesterday, I ventured out and into a rehearsal room here in Taichung to record live drums for Chris Bailey and my upcoming Suncake Lounge Vol. 2 album. I always have a little trepidation when working with live drums, because I’m so used to working with drum loops. Recording live drums and working with the resulting seperate drum tracks is another beast altogether. But I like to think that there’s no right or wrong way when it comes to recording, as long as you end up with usuable results – and in this case we most definitely did.

Make your own photo slideshow at Animoto.

Drummer Dave Ramey kindly agreed to drum on the album on very short notice and very little time to prepare. He did a sterling job though and we powered through the 15 tracks with a single take for each. I’ll probably end up cutting loops from the recorded material, taking care to keep most of the fills and flourishes that Dave added – these have really made the tracks come to life.

We worked with the kit that was in the rehearsal room. It’s obviously not the best kit in the world, but I really like the flavor it brings. There’s something loose and vintage sounding about it. The same goes for the room itself – it’s not going to give the same results as a dedicated drum room, but it has its own character.

I brought in my M-Audio Fast Track Ultra and recorded on 5 tracks straight to Sonar X1. I miked the snare with an SM-57 and the kick with a locally made Superlux PRO218A that I bought for this session. I used the Zoom H2 Handy recorder as a stereo overhead. Finally, I had an Audio Technica AT4033 a couple of metres back as a room mic. Now that I’m mixing the drum tracks and after working in detail on the seperate kick and snare tracks, I’m finding the room mic really useful for blending the sound back together and adding some cohesion again. I’ve also added a dash of reverb from the freeware epicVerb VST, again to add a sense of cohesion.

So far I’m pleased with the sound of the drums in isolation, but there’s still going to be a lot of fiddling to get the drums to suit each individual track. I may also blend in some of the loops that we’ve using for the tracks up to this point – just for variety, if nothing else.
