Within a year either direction, a few other key things happened: The speakers, and the audio input on the HS-60, were especially useful because I didn’t have anything more than a cheap cassette radio boom box for audio in my room. This was affordable by a teenager working for minimum wage at a grocery store because no one wanted analog synths back in the era of the Roland D-50 and Yamaha DX-7 (and shortly after, the Korg M1). The HS-60 was a Juno 106 inside, with all the same electronics, but with speakers and front panel ink designed more for the home organ market. My personal history with MIDIīack in the second half of the 80s, I got my first “real” synthesizer: a Roland HS-60. Or just wait until the next posts where I’ll share more technical details. If you want to skip all that, feel free to head down to the bottom of the post where there’s a brief intro to the new Windows MIDI Services and a pointer to the ADC session. Warning: The first half of this post is going to be more of a personal retrospective rather than a product or project focus. With all of this in progress, it’s a good time take a look back at some personal history with MIDI, and prepare for what the future will bring. The 40th anniversary of MIDI is coming up, and here at Microsoft, we’re working on our MIDI 2.0 implementation and stack updates with some help from AMEI and AmeNote. but if it's another piece of hardware, perhaps just sending the data directly to the hardware with that display might be simpler than sending it to the computer which then retransmits it to the display.November 10th, 2022 6 7 MIDI 40 and the new Windows MIDI Services If that's an on-screen display on the computer, then of course you need to get the data back in. But you mentioned a goal of "displaying preset name on the controlloler's 4-digit 7-seg display". To get it back into your computer, you'd need a separate USB-serial converter. It's probably much easier than using note on/off or other normal MIDI messages to send ASCII data.Īnother option, which probably isn't very desirable for USB, would be using the hardware serial port. If your software can deal with sysex messages, that might be the easiest path. Within MIDI, the System Exclusive message is the normal way for sending these types of non-MIDI messages. The hid_listen program is probably a good starting point. Each operating system has very different APIs. #2: You could use the native HID APIs to directly receive the data. That's how the serial monitor does it when using a USB type without serial. #1: You can use the "teensy_gateway" program and then telnet to 127.0.0.1 port 28541. This might be useful, but it's not simple to access without the serial monitor, because it not a serial device (Mac, Linux) or COM port (Windows). So you can put Serial.print() in your program and it will print to the Arduino Serial Monitor. Teensyduino emulates a serial connection using HID for all the USB types without Serial. Without editing the core library, you still have a few options. It's much easier on Teensy 3.0 (see the comments in usb_desc.h), but also possible on 2.0 with some programming. You'll need to modify the USB code, which involves digging into the core library and hacking the code. It is possible to have both USB serial and MIDI, but Teensyduino currently does not have any option to implement this. If this is completely imposible, I can design a "protocol" for sending back the ASCII data encoded as MIDI notes I've heard about composite USB types, and I am kind of programming something, as I've seen before here. Maybe the limits arise when you have to select USB type at Arduindo IDE. What may happen if you also call Serial.begin(9600) on setup and use the serial communications functions? I have seen in code samples from this page that USB MIDI is programmed only by calling ndNoteOn() and other functions directly from the loop function. I have a program that reads in which preset is active and sends 4 ASCII chars back to my Teensy for displaying preset name on the controlloler's 4-digit 7-seg display. My question is, Can I use the USB serial communications while I am using USB MIDI? This is for a MIDI controller for Guitar Rig, a virtual-amp VST plugin. And I also found another similar post in this forums, but didnt have any reply. So I am only asking based on what I've learned from the teensyduino section of this page, and some Arduino code from the Internet. Going thru my case, I have my Teensy shipped but It didnt arrived yet. Finding something like Teensy clearly made me order one of your boards inmediatly, although having looked at Arduino, which is both worse and more expensive. and I always been interested in electronics and networks. Before I say a single word I want to congratulate Paul and all the Teensy community for the hard work done, I am studying Telco Ing.
