# pip install python-rtmidi

Does work on windows (tested with [[anaconda3]] and [python 3.9](Python39))

Install with
```bash
python -m pip install python-rtmidi
```

### Fixes

I had to
```bash
sudo ln -s /usr/lib/x86_64-linux-gnu/alsa-lib /usr/lib64
```
in order for it to work on one of my Ubuntu 22.04 laptops.

## Simple midi input logger
```python
from rtmidi import MidiIn
from time import sleep
midiin = MidiIn()
for i,x in enumerate(midiin.get_ports()):
  if "M32" in x:
    n = i
    break
else:
  print(f"Couldn't find M32 port")
def cb(e,x):
  data,t = e
  print(data,t)
midiin.set_callback(cb)
midiin.open_port(n)
try:
  while True:
    sleep(1)
except KeyboardInterrupt:
  exit(0)
```

and then press keys. So
```python
from rtmidi import RtMidiIn
pat = "M32"
midiin = RtMidiIn()
for i in range(midiin.getPortCount()):
  name = midiin.getPortName(name)
  if pat in name:
    midiin.openPort(i)
    break
else:
  print(f"Didn't find port with name containing {pat}")
  exit(1)
def cb(*xs,**kw):
  print(xs,kw)
midiin.setCallback(cb)
# and then press keys and turn knobs
```
