FYI: MBSID CS panel ordered

Nomical · June 21, 2003

Current solution: there is a table which allows you to assign
the controllers. For changes you have to upload the whole
application.

Is this done by assigning the functions to a certain button/pot or encoder by the use of a number that's pre-assigned (in MIOS application code?) to a button/pot/encoder?

You said there currently isn't any room in the PIC to implent the 'MIDI Learn' function. And that this function is available for the 16F8xx series designs. Wouldn't it therefor be possible to implent this myself in the application code if i start to make my application from scratch? Wouldn't a simple copy and paste, with some code changes for the new PIC routines, this code into my own code? This is because my own application would take less space as your SID application. Or isn't this possible, because it has to be a function of MIOS itself and not of the application and beside the MIOS (v3?) and the application there isn't enough room on the PIC for this?

Since I will port all PIC16F firmwares to MIOS, you will have some very nice examples sooner or later. However, the integration is already possible and very easy: every MIDI event will be notified in USER_MPROC_NotifyFoundEvent

;; --------------------------------------------------------------------------
;;  This function is called by MIOS when a MIDI event has been received
;;  which has been specified in the CONFIG_MIDI_IN table
;;  Input:
;;     o number of entry in WREG
;;     o first  MIDI event byte in MIOS_PARAMETER1
;;     o second MIDI event byte in MIOS_PARAMETER2
;;     o third  MIDI event byte in MIOS_PARAMETER3
;; --------------------------------------------------------------------------
USER_MPROC_NotifyFoundEvent
      return

you have to copy the received bytes into variables which then will be taken by the MIDI learn function to assign the event to a button/knob/encoder or whatever.

If this info is not enough, please wait for the ported firmwares

Best Regards, Thorsten.

Nice looking panel. 8)

Those knobs are rocking! Cool one, TK. And really slim thing, too.

Looking forward for the first demo MP3s!

And also looking forward for me having enough money to get the encoders and PCBs I still need....argh.

TK. · July 4, 2003

In the meantime I found some time to continue with the case. But there are still some issues which have to be solved:

due to the 9V output voltage of the C64 PSU and the high current consumption caused by the LEDs and the backlit display, the 7805 gets extreme hot and therefore requires a big heatsink (or just a large metal plate)
I haven't found a good solution for mounting the Audio & MIDI plugs, as well as the USB socket at the backsite yet
there isn't so much room in the C64 case for more extensions anymore

However, here a snapshot of the current status:

I've also created a first demo, it's a remix of an older song originally arranged with MIDIbox64SEQ and an AN1x synth.

In the remix everything you hear (beside of the Synth Toms in the background ;-)) comes from a MIDIbox SID . Not all sounds are played at the same time, the tracks have been recorded successively.

See^H^H^HHear http://www.mp3.de/frequencies

"Floating Sequences (SID remix) Part I"

I'm not very satisfied with the results... the new (more powerfull) sounds and the old sequences are not really matching - just because the original composition hasn't been made with a MIDIbox SID ;-)

Part II is planned, and this demo should give an impression of a new feature: an external Moog filter!

I'm in contact with Dirk Lindhof who has a lot of experiences with modular synths - here a link to his homepage http://www.msc175.de/. He will send me a PCB of his 24db Moog filter module in the next days.

The MIOS based MIDIbox SID (later also MIDIbox64SEQ) will support an interface function to the MAX525. This DAC provides 4 analog output channels with 12 bit resolution, it will supply the control voltage (CV) for any external extension. Of course, the 4 channels will also be integrated into the modulation matrix, and they will be controllable via CC :)

Best Regards, Thorsten.

P.S.: StepC is available for download...

Wicked....can it get any better???....looks like I'll be getting an Oakley Equinox then....

pay_c · July 4, 2003

Hey, thats cool! Although I already have an analoge moog filter... cant miss a second one.

Because of the room: I used this with my MB64 for future extensions, perhaps you could use it as well:

I just brought all unused in/outputs of the core (and a few left ones from the DOUTs/DINs) to some kind of extension slot (its a PCB connector, 32 pole). If I gonna need that stuff, IÂ´ll just put it into a second case, which looks like the first one (only smaller).

Perhaps this with the SID?

stryd_one · July 4, 2003

Oh my giddy giddy gosh!!! :o :o :o

I wonder if I'm the only one to notice...the combination of these two new features - an analog filter module, and a CV output... The CV out could be used to control the filter module... All MIDI controllable, and LFO's and ENV's would be a piece of cake....

Can anyone say Sherman Filterbank?

I am officially droooling ;D

Now all we need is a sampler... Don't ask for much do I? heheheh ;)

Steven_C · July 4, 2003

Oh my goodness! My jaw really dropped when I saw those pics! Thank you TK, for sharing your adventures with us!!!

BTW, I have a simple VCF circuit somewhere if someone wants it... based on the (old) ca3080 dual transconductance op amp (though it may be hard to find this chip now)

:o :o :o That looks friggin' amazing.

That is MIDIbox of the week for sure ;)

if you go in this way all the time , i think i sold my ELECTRIBE EA-1 ;) ;D

:o :o :o Â That looks friggin' amazing.
That is MIDIbox of the week for sure ;)

From now on, I suggest we introduce some "SID Synthi of the week" Topic as well!! ;D

Mine will be finished August or September. It will have about the same controlling layout (I just copied it... ;) ), but a completely different case and design.

Steven_C · July 5, 2003

I have some ultramatched transistor pairs, and other bits that I was going to use for a diy moog filter once, but the pcb I was going to buy went out of production... but how hard to build is your filter project Thorsten? Does it use hard to get parts? I'd like to use the bits I have, if I can... or maybe you can put them to use Thorsten? Can you easily get the bits you need?

BTW nice knobs! (from Waldorf, I assume, from months back someone did an oder I think I remember!!)

DrBunsen · July 5, 2003

Congratulations Thorsten, Â the new front panel looks a treat! Â I'm so building one of them now.

And I'm very happy to hear that you are designing a CV out module for the SEQ unit. Â I was waiting for the forums to come back online last week so I could do a search for that very thing.

Yay x 9

;D ;D ;D

When you orginally showed the front panel design for the SID synth, I thought the modulation matrix was buttons, not LEDS, for instant patching. Is that possible?

The Australian electronics supplier Jaycar sells a nice line of miniature push buttons with LEDs inside them.

Steven_C · July 6, 2003

Hey Dr B...

I bought one of those $0.80 very cheap alps LED buttons to try, but I didn't buy anymore, as

(a) they need a square hole to look neat (more work)

(b) The main problem is that the LED is deep down in the switch, and you need to look straight down from the top, to see if the LED is lit or not... Though maybe the clear plastic lid can be frosted, to diffuse/disperse the light from the LED so it can be visible from an angle? (frosted by use of a bead blaster, on the back of the removeable clear plastic top, but would be very tricky, and I wouldn't want to do more than a few by hand....)

chriss · July 6, 2003

hello,

all that sounds so nice, my next two years are planned.

Hope that Thorsten is slowing down so we can catch up a littlebit.

Unbelievable.

chriss

TK. · July 7, 2003

Thanks! :)

I don't want to start a seperate filter project, my analog skills are low, and there are a lot of functional circuits available in the web. The CA3080 is still available, but very noisy. A multi state filter based on the LM13700 gives better results (I built it some years ago, unfortunately I've no idea where in my flat (or possibly in the cellar?) I can find this board. ;-)

However, a Moog cascade filter can be build with common general purpose transistors, just only the resistor values have to be adapted.

I will start a new MIDIbox SID analog extensions page in some weeks and add some links to other websites which are specialiced on analog DIY stuff

DrBunsen: yes it's possible to replace the 15 select buttons by a matrix of 64 buttons, but this requires some (rel. simple) changes in the firmware. However, I prefer the existing solution, because it's smaller. It doesn't make a big difference from the ergonomic point of view, because mainly you want to see which modulation sources are linked to the targets, the buttons are only used for the configuration, and this will normaly not be changed that much during a playing session.

On the other hand: this control surface is not the ideal solution for everybody, our workflows are too different - other variants are welcome! :)

Hope to see some nice cases, but especially to hear some great SID tunes in the next weeks/months! :)

Best Regards, Thorsten.
