Very cool! Thanks for the link. Do you think the bugs are perhaps related to the rhythm instruments? I need to make some updates there based on updates in the...

I have a feeling the OPL3 issues you are experiencing have something to do with how the second register bank is mapped in your port. I can play OPL3-based music...

Digging up this old thread. Were you using register_file_axi by any chance? That module is untested. I ended up using and modifying the device memory map generated by Vivado (under...

Some clarification on the 6 waveforms in the OPL3: - There are only two ROM tables in the OPL3: 1/4 of a log-sine wave and an exponential function - The...

This might be due to the levels being too high. I've experienced the same thing on my zybo and had to lower them. You can decrease the volume by modifying...

For one thing, the output digilent chose to use on the DAC is the amplified headphone output. Wished they chose the line out. Greg ⁣Sent from Blue ​ On Aug...

OPL3-FPGA can now be used as an output device in DOSBox which should run AT2 thanks to the work of Walter van Niftrik: https://github.com/waltervn/opl3_fpga-apps I've got it working with the...
