Userspace driver for Dreamlink roll-up drumkit

Userspace drum kit driver

Just bought for fun one of those drum kits in nearby thrift shop. Wrote this program because all existing ones (drumroll and jackdrum) didn't work with my drum kit, and were using libusb-0.1 which is deprecated, and didn't have loop buffer which is cool, and one of them used math.h only to do pow(x,2) but not simply x << 1.

All info necessary to determine endpoint got from lsusb. Some things may differ between different drum kits.

Usage

To gracefully exit program send it either SIGINT, SIGHUP, SIGTERM or SIGQUIT, eg. press Ctrl+C in your terminal.

Larger values of loop buffer will increase time spent at gathering data from drums, so it can minimize false release action. Big values will cause specific delay.

To check how note number and actual drum sound corresponds look at http://www.midi.org/techspecs/gm1sound.php

Pad numbers in my case were:

1 3 2
6 5 4
