Introducing the x0xb0x

x0xb0x = Synth + Sequencer

The x0xb0x is not just another MIDI-controlled TB-303 clone. x0xb0x is a full reproduction of the original Roland synthesizer, with fully functional sequencer. The sequencer can be programmed just like the original 303 (ok its actually a little easier, we think) and can be used to control other synthesizers via any of its various output formats. 128 banks of track memory and 64 banks of pattern memory are stored in onboard EEPROM, no battery-backup is needed!

100 b0xes of x0xb0x on the wall

The x0xb0x (Adafruit edition) was available as a kit that includes all parts necessary to build a x0xbox: PCB, case with CNC machined faceplate, components, buttons and knobs, AC adaptor, pre-programmed microcontroller, and (of course) poorly xeroxed assembly manual*...You supplied the sweat & tears.

We have made 9 runs of 100 kits each. All but one of the components in the kit are through-hole.We had a great run and we are currently exploring how to best support this project in 2010 - so far we've made the project completely open source and we will have more updates in the month of April with what's next for our role with the x0xb0x.

Because of demand and time/cost to make these kits -starting in 2005 we created a "waiting list" where interested kit makers could sign up to be notified if and when the next run was available for purchase.This list was a "spot in line" for the kits Adafruit Industries may make based on pricing, time and demand. We did not accept any payment in any form until the kit was shipped and the listee was notified to place their order with a special password for that run. This worked out great, we never "held" funds unless a kit was sent. The waiting list was simply a "back in stock" notifier for potential x0x customers.

At this time (4/2010) the waiting list is closed and no longer will be used. Our data retinition policy for this list is mas follows -- We do not retain email addresses or names, if you signed up you can safely assume the list has been deleted, you will never be contacted by Adafruit or anyone else. We hate spam.If you have any questions please email support@adafruit.com

Before you email us with your question, read the FAQ and search in the forum. If you have a question, please ask it in the forum!

p.s. x0xb0x is spelled with two zeros.

p.p.s. x0xb0x is pronounced "zocks box"
