I nearly had the synth working last week when I ran into some timing issues. I ordered faster parts but they just came in today and I'm busy with a contract project through the weekend. I hope to post a video sometime late next week with Ultrasound playback working - hopefully in Inertia/Cubic/FT2, Doom, Descent, and the like. I am making a concurrent change to a second spin of the prototype test board which has HyperRAM instead of SRAM - which will also require yet another refactor of the ISA bridge for write caching. So it actually may be mid-August depending on problems/delays.
It will not be Interwave pin compatible. The core will run on an ECP5 as part of a larger all-in-one sound card project I'm publicly launching next month.
I hope to have the 'big four' working for my table at VCF-MW in September which includes SB16 DSP in a soft core, Ultrasound/InterwaveLite in a soft core, intelligent MPU-401 (soft core) with an attached Dream SAM5504B eval board, and OPL3 which will actually be an external hard OPL3L for now until the OSS issues are worked out. Eventually will be every sound card standard + storage + RAM back-fill + WiFi (NE2K compat) + speaker snooping + integrated Dream SAM5504B + Waveblaster header + USB/SPDIF output on one ISA or MCA card (yes, I said Microchannel). My talk at VCF-MW in Chicago will publicly launch the project with (hopefully) a Kickstarter in early 2020.
