Audulus Audio Sampler - 512 Stage Bucket Brigade Chip

Mark Boyd posted this example of an elaborate delay line using 512 stages, similar to classic Bucket Brigade effects. This patch can be downloaded for free from the Audulus forum.

Video Description:

This is a model of a 512 stage bucket brigade chip. Essentially, it is an expansion of the Control Signal Looper - but instead of 8 steps it has 512, making it suitable for capturing and looping quick bursts of audio.

Make sure you play with the max step number - increasing it past 512 basically gives you a PWM wave. Also make sure you modulate the trim of the Saw wave, or even try attaching a Sine or Triangle (just not Square).

Snekula - Born

Reader Snekula did another awesome track, with a creepy video. This track was done entirely on Samplr. For those of you worried, like me, he reports that the beetle was eventually flipped over and went on his way unharmed.

Drums by Asrodot

Reader Arno Van Goch, aka Asrodot, is recovering from two years of serious health problems that hindered his ability to continue iOS development. He emailed yesterday with some good news to let me know, "I again fully enjoy working on apps, and I am full of new ideas!" We're getting the first sign of that in this update to his Drums app released in 2013!

What's new in Drums by Asrodot v1.3:

After a long struggle with health problems I am now finally able to release the latest update to Drums by Asrodot.


  • Inter-app audio support
  • Added a simple yet powerful loop recorder. You can now record multiple layers of drumloops and export them to iTunes, AudioCopy or Soundcloud.


  • Problems with using AudioBus

Happy Drumming,

Buy Drums by Asrodot on iTunes: $1.99
