SID SYNTH - 'prog_uchar' does not name a type

Can anyone help me please.

This is the error message I get when I try to upload the code to my Teensy 2.

'prog_uchar' does not name a type

What does this mean please, baring in mind I am a beginner.

I'm trying to put together the SID Synth as found on Git.Hub.

Also, my Mac is doing some weird things when my Teensy is plugged in.

Has anyone built this synth and can anyone help please.

Many thanks,

Paul

I can see nothing wrong with the code that you have not posted.

'prog_uchar' is an old way of saying 'const byte PROGMEM'. The code you are working on has not been updated for a while. All of the variable types starting with 'prog_' were removed around V1.6.0.
