![]() ![]() adding in merge from buttons etc is nt going to be much of a step. Here is a link for USB midi to serial midi. ![]() what do you need to send to keep sync / update transport speed, midi protocol wise? That could be 'tricky'? while you may be sending midi messages "at the same time", don't you need a MTC / MMC- type master to stop drift? Just starting them together is not really good enough is it? I've not investigated that in the teensy context (cause I've never synced two sequencers. adding in your software merge is not going to be a problem. ![]() Īs to sliders and buttons, I use 13 buttons and one motorised fader myself, outputing usb midi. I'm not sure about running 2 midi out ports off one serial line, but seems OK (I've never done it myself). Midi thru is pretty easy and midi out hardware is really easy. I didn't know that midi called for a ferrite choke!! I have successfully used this circuit (no choke). I also started to get confused which pin the midi should be coming out of to go to the PC900. ![]() The MIDI guidelines also recommend adding some ferrite chokes on the pins to the MIDI socket- I just didnt draw them in.Īnd I don't know for sure if I got the Diode or the Capacitor around the right way. I have used a sharp PC900V for an Optocoupler - as recommended by the MIDI specifications, and put a power regulator on the input for safety. Mine differs a little because I want the Teensy to absorb all the data from the In, merge any potential data from the USB or buttons/knobs/faders and Output that to the Outputs.Īm I doing this right? Is this making sense? Or am I totally lost! I am not circuit savvy but have looked at the midi specification to see how to do a MIDI-Out/Thru circuit and a MIDI In circuit. I have used the analogue ins for the buttons but I believe these could be bumped to the digital side? Its just the Pots and Faders that need to be on the Analogue side?Īnd as for the rest of the circuit - will it work?! Ok, This has taken me all day to draw! Well, not to draw, but to find a program to use and figure out how to use it! I would rather have it all in one compact box! It would be fantastic for me to have one box that does it all and is flexible in its uses rather than doing everything independently - It creates so much clutter having a controller and then a cable to a splitter and then a USB interface. I plan on adding a 5V power in (so would cut the tracer from USB + Pads on the Teensy so that all devices get their needs met in the chain: the Teensy and 2 x MIDI devices).ĭo you think that is possible with just the Teensy? I have found MIDI controller tutorials and Midi to USB tutorials using the Teensy, and MIDI splitter tutorials (without the teensy) but am unsure of how to combine them all.Īnd how many Buttons/sliders would I be able to have on my controller after allowing for the other ins/outs? I would probably just max it out for future uses. There are many tutorials on how to do this with the Teensy, but I would also like to incorporate some other functions which would be very useful to me.Ī MIDI in (So I can use the device as a stand alone Midi - USB converter when I need it)Ģ x MIDI Out (Again so I can use it as a USB-MIDI device PLUS send the Controller side of it out PLUS act as a MIDI Thru port from the MIDI in AND an output from the USB MIDI. These can be generic on/off Midi commands or MMC commands). I would like to make a controller to give me basic functions like "Go/Play", "Next", "Back", "Pause" and "stop" (Like a glorified old school tape machine AND maybe a pot for Master Volume control. I am a Sound Engineer and often I am required to run two Mac based sequencers in sync with each other. ![]()
