NI404 - using MIDI as input (short demo)

video upload by SOUNDPAULI

"Just a short video on some new features:

0:25 I recently updated the code to support USB MIDI as input on each of the 8 channels.

2:22 Also, I added the possibility to change the start of a sample on each voice - to be more flexible while building.

The Device is open source - so build your own!

Building a track from scratch with the open source NI404 sequencer from soundpauli

video upload by SOUNDPAULI

"Today I show you how to build a simple HipHop loop with the NI404 open source sampler/sequencer from soundpauli.

Choosing the samples, putting them on the voices, plus fidgeting around with the tracks and samples while playing in live-mode.
Enjoy!

(In the background you hear my old dishwasher - sorry for that! :D)

I'm currently hard working to get new PCBs and casing done - so you can purchase an already assembled NI404 - sadly, this takes a while. If somebody is into PCB / KiKAD and likes to contribute: I could need some help!"
