Thinking about making an FM...

Hi

Im somewhat new here, although Ive been hovering over this midobox resource for months now. Ive decided that having a midi synthesyzer would be nice, and due to the lack of SID chips avalable, I think Id rather use the Yamaha alternative and make a Midibox FM. The only problem is, Im a noob. Id like to ask for help to get started, but first I have a few questions. First off, Im wondering why there is such a lack of knobs on the FM photos Ive seen so far. The program for it has a whole bunch of tweakable features, and Im wondering if for some reason the knobs were just not put there because the builders just cose not to add them. Im the kind of person who likes to have all tweakable features right infront of me, so Im hoping that a midibox FM can have much more knobs. Id like to do less of my knob turning on the computer, and more on the box itself. Unless I really dont know what Im talking about and more knobs is just a silly idea, and in that case you can set me straight. Im also wondering if you can put more than one yamaha chip inside of the FM, like how you can have four SIDs inside of one box. Is this possible? Is this reasonable? I seriously want to have a synth where the majority of tweakable features are presented to you on the interface itself, so if this isnt remotley possible with the FM and Ill end up spending more time on the computer than on the synth itself, then this project isn'f for me. But, Im very optomistic, and would love to get started as soon as possible.

Thx, Evan.

Check out this page: http://www.ucapps.de/midibox_fm_manual.html

You can adjust all the parameters with the control surface, you'll have to navigate within the menus to select what you want to change. If you want each setting to have it's own knob then I believe you can build a MIDIbox64E and have it send cc's to the MIDIboxFM.

A single OPL3 already provides so many voices, that there are 4 independent instruments + 1 drum channel available. This saves you from building 4 core modules, and I don't think that you really need much more than one OPL3 in your setup. The number of knobs was my design decition, the firmware isn't prepared for more.

But you can add a MB64E before MBFM if you want, the available CC parameters are documented on the website. This adds a latency of 1 mS

Best Regards, Thorsten.
