Default Midi C1

Hi,

I just got my Reaper to play my Casio and I noticed that my keyboard C1 was not the same as Reaper´s C1. Should I change my keyboard or is there a setting in Reaper (which I think it is), that I could tweak?

Have a nice day,

Espen

In Reaper, the default MIDI note naming range is C-1 (MIDI note #0) to G9 (MIDI Note #127.

Many people (and plug-ins) use the name range C-2 to G8.

You can change the name range in Reaper's Preferences / Media / MIDI: change the "MIDI octave name display offset" to -1.

Hi Darkstar, thanks for the reply.

I tried it now, but it made no difference. I even restarted Reaper, which I normally never do.

I´m quite new to using midi in programming, so I just assumed that middle C was C1. Is it C4 that´s middle C then?

Middle C (MIDI note #60) is named C3 or C4 or even C5, depending on which naming convention is used.

Exactly which Casio keyboard are you using? You will need to find out what MIDI note number it is sending whee you press the "C1! key.

Add the JS FX to a Reaper track, play some notes, and look at them in the Logger. The second to last column is the note number (in hexadecimal)

Hi again,

Im getting 3c as the key pressed when I play middle C on my keyboard. It is a Casio CTK 811-ex.

I tried attaching a screenshot here, but I dont know if it got uploaded.


(how do you get those colours on your midi log?)

Hexadecimal 3C is 3 * 16 + 12 = MIDI note #60. That is middle C.

OK, now what do you want to name it? And what name does that note currently have in the MIDI Editor?

The MIDI Logger colours were added in a recent release I think
