Music on the MEGA65 in BASIC65

adtbm · Sep 26th 2021

While we reached an excellent status with the current MEGA65 ROM i would like to present you

the latest addition: the PLAY CMD.

How many of you started programming in BASIC and were disappointed, that when it comes to music and sound, the BASIC is so limited that you only can run the music routine inside the main loop.

Depending on actions and more in this main loop the music changed temp, stuttered etc.
The new PLAY CMD will start a tune or sound effect inside an interrupts and will not disturb the execution of your games main loop anymore.

I'm really looking forward to code some games in BASIC. There is something charming about BASIC programming, and having improved and usable functionality will make it much more interesting.

Maybe someday we could release a nice BASIC type-in magazine for the MEGA65

I hereby pre-order 2 copies of the first issue.

Just a question, as you're demonstrating polyphony here - how does the SID channel get selected?

I just looked at the play sequence and my guesses are:

- O5 = octave #5

- I = eighth notes

- Q = quarter notes

- R = rest

- L = loop

- ABCDEFG = notes

I have no idea what "." means though, and I also don't know what "T0" means. And I don't know what defines the SID channels to be played on. Could be the "T0" but the sound effects are played on top of the melody, so I guess that's not it.

Take a look in the manual.

ah okay, I thought the PLAY command is so brandnew that it's not in the manual yet

The team is working so hard, that sometimes the manual is updated before the command is fully implemented by Bit Shifter (or Gurce with the PLAY command).

Great info! But, I’m afraid it’s posted in the wrong channel. Should be in the BASIC65 section, not BASIC10, adtbm

additional note: can “BASIC (M65 Mode)” please be renamed/corrected to “BASIC 65 (M65 Mode)”?
