  • I know I'm too late to the game, but here is what I wish I could have written 4 years ago..., and maybe it will inspire an upcoming cartridge or rev 2.

    In addition to SIDS and digital audio, add Memory Addressable Analog Filters at the Audio Output Stage.

    -----------------------------

    To me as a musician, the soul of the Commodore was the sound. It's what drew me in. Lately I've been learning about SID chips and the unique fact that they had analog filters. I keep reading that the analog filters on SID chips can't be recreated, so don't try. Ok, I get that.

    Currently, the Mega65 will have 4 soft sids, 4 channels of digital audio, and the ability to have hard sids in a cartridge, thus the Mega65 will be able to emulate the sound of the past, and also do a lot more.

    But the Mega65 could also be given a soul of it's own. A new soul that inspires musicians to create. It is the next Commodore. It could have it's own analog filters. It could become it's own thing.

    Take a lesson learned by every modern synthesizer maker today. You can digitize everything, but then stick an analog filter at the output stage and you bring things to life.

    Add Memory Addressable Analog Filters at the final Audio Output Stage after the soft sids and after the digital audio.

    Yes, this is not meant to emulate the old, but musicians will use the Mega65 to create brilliant music. Imagine the new demo scene with sweeping filters. Yes, these filters are not per Sid voice. Instead they operate like a Moog Model D... where audio is mixed into the filters after the sids and digital audio

    Hi and Welcome !

    Thanks for your ideas and suggestions. Like you've mentioned already, we would have needed that

    post roughly 4 years ago. Nevertheless, we've noted your idea down, together with other

    possible ideas and suggestions.

    So we can't promise anything but we took note !

    The reason behind this is, atm the MEGA65 R3 board works absolutely reliable and we have not found any major hardware bugs that would enforce us to revise the current pcb, but since we are still collecting feedback from the DevKit owners, who knows...

    So if, for whatever reason, a further mainboard revision would be required, we will take all those ideas into consideration as well.

    Thank you !

  • I totally understand, and thank you for taking note, and regardless, I will be buying a Mega65 when released.

    Questions about the cartridge signal flow. Since hard sids can be installed on a cartridge, I assume analog audio signal can flow from a cartridge back to the Mega65 to be mixed with the softsid and digital audio signals.

    My question is, can audio flow from the Mega65 softsids and digital audio out to a cartridge to be processed by the Cartridge and then flow back to the Mega65?

  • At this point we have not started on the cartridge-SID solution.

    But i'll forward your question to mega65, he might give you an (theoretical) answer, if your request would be do-able.

  • Because the MEGA65's cartridge port behaviour is much more flexible (its direct connect to the FPGA, with nothing else actually on the "bus") we can do all manner of craziness, including having a DAC and an ADC in the cartridge to cross over into the analog domain, have whatever magic lives there, and then bring it back to the digital domain for output through the MEGA65's existing audio outputs.

    Paul.

  • That's great!

    In addition to sending the analog craziness back into the digital domain, back to the Mega65 for normal output, it would be nice if the cartridge also had analog jacks so the analog craziness can remain analog.

    thanks for your great work!

  • Behringer is doing amazing stuff today, brings us all the good old analog synths back to life and for an affordable price too. The idea in the first post and second with the special behringer chip is really interesting.
