The Roland TB-303 doesn’t have MIDI or CV/Gate to enable external control of its voices. It does have a DIN Sync port that allows it to be synchronised with other equipment. It does have its own CV and GATE sockets, but they are output sockets for controlling other synths. Kenton offers a variety of options to get your TB-303 connected to MIDI, depending on whether you want to control the voices, or just sync with other MIDI equipment.
For current products:
- Sync your TB-303 with your DAW or sequencer
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a Pro-Solo Mk3
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a USB Solo (not currently available)
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a Modular Solo (not currently available)
For previous products:
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a Pro Solo MkII
- Control notes and filter with MIDI using a TB-303 Socket Upgrade Kit and a Pro Solo MkI
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a Pro 2000
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a Pro 2
- Control notes, filter, and optionally accent and slide with MIDI using a TB-303 Socket Upgrade Kit and a Pro 4
See below for further details on each of these options.
Fitting a Socket Upgrade Kit to your TR-303 is a skilled job which should be undertaken only by a competent synth service engineer or fitted by us at our premises in Epsom, near London (UK customers only).
1 – Sync with your DAW or sequencer
The TB-303 has a 5 pin socket for sync input. This will enable you to run the TB-303 in synchronisation with your sequencer. In this mode, you will need to program the patterns you want to play, directly into the TB-303. You will need to program the TB-303 in the normal way, from its own front panel, you will not be able to use any added CV, Gate sockets for programming.
When you start your sequencer, the TB-303 will play the patterns in time with your sequencer. You will always have to start the sequence from the top as the TB-303 will not recognise song position pointers. If you only want to run the TB-303 in sync you do not need to get any additional sockets fitted.
If you just want to sync your TB-303 using the MIDI Clock, see our Converting between MIDI and DIN Sync page.
Note that the SYNC IN socket on the TB-303 can fail as the soldered joints to the DIN socket pins become cracked and require re-soldering.
