Do it at your own risk. You may mess up with Echo's functionality, so be careful about it and make sure you know what you're doing. + + Since version 1.64, writes to register $27 are handled specially: only + bits 7-6 are passed as-is while bits 5-0 are left to Echo. This is + because this register selects ch3 mode but also has the bits that trigger + the timers. This way, streams can change ch3 mode without risking Echo + undoing the changes. ============================================================================= |
