Hello people and thank you for once again reading Paul’s Tech Talk on the ChipWIN Blog!
Today we’re going to finish the two-part article about LSDJ version 5.0.0 and the wonderful new Commands it came with. Last time, we delved into the new possibilities offered by the Pulse [F]inetune Command, so don’t hesistate to read that one first if you haven’t already!
Today, we will focus on the upgraded W command, which can now control WAV channel instruments. Buckle up!
Just like the pre-5.0.0 F command, W already existed in LSDJ before. It was a very handy command that used to work only in the Pulse channel and controlled Pulse [W]idth Modulation (or PWM for uppity initiates, pronounce “Pwuhmmm”). Even though the Pulse channel Width parameter was only limited to 4 values, (12.5%, 25%, and 50%, with 75% being the inverse phase twin of 25%), being able to control it thanks to the W command opened up a lot of bleepy sound design possibilities. Using and abusing this command has always been, as far as I can remember, a staple of the LSDJ workflow.

But we’re not here today to talk about Pulse channels. These have been thoroughly accounted for last time already. Time for the Wave channel to shine! As true as it may be for the distinctive squarewave sound of the Game Boy Pulse channels, LSDJ probably wouldn’t have been nearly as popular if it didn’t allow us to tap into the nigh-infinite power of the Wave channel.
