DIY Mini Sequencer Project
In 2008 Paul Maddox wanted to start building synthesisers again, and not having much in the way of test equipment Paul built a simple 8 step sequencer. This was called GorF and was named after his love of 80's arcade games.
Paul put the video of the early version up on YouTube (http://www.youtube.com/watch?v=df8Q0wIoSRM) which received over 1000 hits within a month. GorF quickly gathered a lot of interest on the internet and won a competition for innovation winning him a zoybar guitar.
At this point Paul decided to make a kit of the project and using the free PCB CAD software called Eagle created a small PCB, 100mm by 80mm. This had all the switches and displays on of the prototype and added memory to GorF. from 2008 to 2011 Paul added a number of features and enhancements and published the code, schematics and PCB files under the GPL license. Peter Kvitek added the Bank Play mode and made a few performance enhancements also.
GorF has the following features -
- 8 steps per pattern
- each step can have a different note length
- each step has -
- Note value
- Step Length
- Note Velocity
- 2 MIDI CCs (user definable)
- 2 patterns can be chained to create 16 step patterns quickly
- powerful bank play mode which allows up to 8 patterns to be chained with the ability to repeat a pattern a number of times before moving the next.
- Updatable via MIDI sysex
over 250 kits have been sold since their release in 2009 and kits continue to sell under the VacoLoco brand.
