+ | SID Testtone generator | ||
+ | |||
+ | This MIOS application generates a simple 1kHz triangle testtone on the SID. | ||
+ | There is no "MIDI Note On" event required to start the sound, you should hear it immediately after the MIOS bootphase | ||
+ | |||
+ | In addition, a 1 kHz pulse will be generated on the CS lines to the two SIDs. This feature allows you to test the output amplifier of the | ||
+ | SID module (unplug SID, connect socket pin #8 with #27) | ||
