The Pro Micro  How to get the projects If you are interested in building any of these projects please contact me for details. I don't supply any parts but you can get the Pro Micro and other parts from eBay etc.  You can contact me via the comments sections. Alternatively,  email me at  gmail - my name is chaz riff but without the space ;) Behringer 2-XM Polyphonic Controller This is the latest project - a four voice controller for the Behringer 2-XM. This is based on the Oberheim SEM which was the synth module that was in the famous FVS (Four Voice Synthesiser) from 1978. This project uses 2 Pro Micros connected via the TX and RX pins. I needed 2 because it requires 32 ins and outs.        FVC connected to 2-XMs More info  here Low Cost Polyphonic Keyboard Controller for mono synths A much simpler and cheaper alternative to the 2-XM controller. Very cheap to build and still has an on board polyphonic ADSR. All controls are handled with CCs f...

Behringer 2-XM Polyphonic Controller This is the latest project - a four voice controller for the Behringer 2-XM. The 2-XM is based on the Oberheim SEM which was the synth module that was in the famous FVS (Four Voice Synthesiser) from 1978. I was lucky enough have one of these (courtesy of the record company!) and used it for live and recording until the mid 80s when it died! I still have one of the modules but the rest is long gone. I had given up all hope of ever replacing it until Behringer announced 2-XM which is a faithful but smaller recreation of the modern SEM (2000s). Each 2-XM is actually 2 SEMS  - can you see why it's called the 2-XM ;)  so if you have 2 units and a controller you would have the equivalent of the mighty FVS. More information about ordering and building  here Here is the finished prototype....

Synth Editors standalone and plugin format Mac and PC for Roland RD88, JU06A, SH01A, Oberheim TEO-5, Behringer UB-Xa, TC M350 JU06A : RD-88 : SHO1A : Pro Solo MK3   TC M350 : UB-Xa : TEO-5 I thought it would be useful to create a single post for my CTRLR panels. There are  Mac and a PC versions: Mac Editors tested up to OS 15 Catalina - reports from users that it works on later Macs PC Editors tested and working on Windows 7  and 10 Mac AU component tested in Live 10 and Logic 10.6  Mac VST created in Reaper tested on Cubase AI 10.5 and Live 10 (Plugins are not compatible with later Macs) Mac Installation Note : if you get the message that the app is from an unknown developer and can't be opened got the Security panel in System Preferences and grant access:  On Windows you will have to allow it to run because the editor has not been verified by Microsoft. Just select More Info and then follow the prompts. Oberheim TEO-5  Downloads: MAC Standalone V2 MA...

Oberheim TEO-5 Editor CTRLR Editor for TEO-5 TEO-5 Edit V2 I have added a 3rd Tab to the editor which gives access to some of the sequencer and a simpler editing page based on the SEM called the Semulator: MAC Standalone V2 MAC AU Component V2 (Intel Only) MAC VST V2 (Intel Only) PC Standalone V2 V2 includes the original V1 editor  Main Editor Page Matrix Mod and File Page New editor page giving you a simple 16 Step Sequencer and a SEM editor - the Semulator The sequencer is useful for recording and editing monophonic lines - might do a full polyphonic version but not sure I would ever use it. The Semulator is just a bit of fun and just gives you access to the same controls and modulators of the original SEM. It's best to start with a basic program and use it like a soft synth. Note that VCO1 and 2 are swapped around because on the original SEM VCO2 synced to VCO1 - on the TEO it's the other way around.   The modulators specifically use the first 3 slots of the MOD MATRIX - ju...
