David Robillard d357eca668 Factor out sequencing related things into an independant new library: "evoral". Anything related to the storage of events/values over a range of time lives in evoral. This includes MidiModel (Evoral::Sequence) and automation data (AutomationList (Evoral::ControlList), Automatable (Evoral::ControlSet), etc). libs/evoral synced with http://svn.drobilla.net/lad/trunk/evoral r1511. git-svn-id: svn://localhost/ardour2/branches/3.0@3754 d708f5d6-7413-0410-9779-e7cbd77b26cf		2008-09-19 00:47:49 +00:00

README

This module works with the Griffin Powermate and allows some basic transport control.

It autodetects the Powermate on any input device of the form "/dev/input/event*".  This means you must have the powermate module in your kernel.  It works out-of-the-box with 64Studio and presumably lots of other modern distributions.

Turning the wheel left and right will act as a "Shuttle" wheel, adjusting playback speed up and down
Pushing the knob will switch between play and stop
Pushing the knob while turning will jump to the next or previous markers


In order for the powermate to work, you have to have permission to open the input device for reading.
In debian, I changed /etc/udev/rules.d/0_permissions.rules to have the line:
KERNEL=="event[0-9]*", 		MODE="0666"
but there are other ways to achieve this


Feedback, tweaks, bug fixes and feature ideas are encouraged
