Bankstick Selector - another attempt !

Design Concepts
1

Hey there!

Actually some questions and remarks:

Would there be an interest for a PCB of a Bankstick Selector based on the design of drDRM (a little upgraded & debuged by me)? (GREETS to you DRM!)

It would be a hardware solution, which has nothing to do with MIOS or so (MIOS also has a solution implemented, but up to now its not used in any application).

Specs: Up to 6 banksticks can be used (You naturally can also connect external ones) and the number of them can be set with a jumper. A push button is used to switch thru them (if the next step reaches the number of the jumper the Selector will jump back to Bankstick number one). The actual Bankstick is showed by LED.

The system is MBHP compatible and so can easily be connected to the core.

Tell me what you think. And also if you understood the weird explanation of above…

@drDRM: Perhaps you could post the schematic of the 4 Bankstick version, so everything gets a little clearer.

Sounds great! But, won’t MIOS be supporting this kind of functionality in the future? In other words, do we need a new PCB for this?

drDRM, I would love to see the schematics. Maybe I can already put 4 led holes in my frontpanel design, which I am working on now…  :)

Yes, MIOS is already supporting it. But it isnt used in any app up to now… so just take a hardware solution and youre out. *If* you want to.

As soon as the protal is online, I’ll put the PCBs & the newer schematic in there if needed/wanted.

Bankstick switching is already supported by the MIOS based MIDIbox64 (beta) and it will be supported by upcoming derivatives (MB64SEQ/16E/MF/NG), and by the next MIDIbox SID version of course.

Just for information… :wink:

"ve been away for a while, so i’m a bit late with responding.

I’m busy with the bankstick selector. I’m testing it on a breadboard, it almost works. As soon as it works, I’ll notify it here, and i’ll will also put the schematics on my website. So details will follow.

Please consider that a hardware based BankStick switch won’t interact properly with most applications: reads and writes to the EEPROM could be interrupted (MIOS will reset the core if this happens during a write) and the program won’t load the new bank automatically

Best Regards, Thorsten.

Hi,

Her is my schematic, as promised. I tested it and it works :smiley:

Nevertheless I’m planning to use the solusion TK mensioned, because it’s more “foolproof”.

I hope that you can use this schematic Pay_C. Maybe you can share your upgraded version when it’s ready.

Success with it!

regards drDRM

Hmmm, as TK said, I think a hardware solution isn’t useful anymore.

Especially if you take a look at the Midibox Roadmap. Those 8 banks are OK, and much more easy to implement…
