Hi Thorsten, thanks, but I did build a cs in the end, figured it would be worth the extra effort, especialy considering the effort you put into this very complete software. Best regards Alex

Hi There, I Have just finished building my first analog modular synth based on the ASM2 http://www.elby-designs.com/asm-2/asm2.htm And have built a basic Core/aout_Lc for converting midi to cv. I dont have a spare lcd or buttons for the control surface midibox cv offers and dont need anything more than a 1v/oct 8bit cv and gate for midi ch1 and another for ch2 anyway, so I was hoping to pre-set the variables accordinly to my needs and recompile the .hex. could anyone tell me what variables need changing (appart from the obvious hardware config settings in main.asm) to meet my synth's requirements, and what the default note range is etc . If i get these right, I guess I could tune the aout by ear playing the same midi on a soft synth oscillator... I'll try to find a new lcd if the control surface is absoluteley necessary, but it seems a pitty to have to add buttons, lcd etc to a device that is hiding under a panel... :-\ Thanks for any suggestions Best regards Alex

Hi, I just used a Din pin for each of the 25 keys of my Sid/piano, I had a spare DIN 4X module handy and couldnt be bothered with matrix coding. I can send you my complete Sid project files if you want, allthough they are a bit messy. I'll try to document both my Sid octopus Etch a sketch LFO(http://www.midibox.org/forum/index.php?topic=7595.0) on the wiki as soon as I have some time to myself!!! ;) cheerz Alkex

Excelent woodworking/design, reboot!!! Congratulations

Hi, I would suggest simply using a stereo Pot. Wire one channel to the Ain, the other to the led.This should work Best Alex

Hi Folks, Just thought you might be interested in this little toy I'm working on based on the Mios platform: A midi Lfo with "Etch a sketch" style realtime waveform drawing. Basically you have a 14*10 dot matrix display of a waveform you can draw and edit with the silver bottom knobs. The Four Double pots control speed and depth of each of the Four Lfos. Leds beside knobs flash at rate of Lfo. It is in early stage but I will be working on the following other the next week: -Realtime "averaging" of jumps (portamento) -sequencer mode for note outputing -try to sort out an easy way to put decay on the pulsing leds so they appear to fade out. -make a nice wooden chassis. I'll happily give my code to anyone interested, allthough It's very teadious and clumbsy (but I'm learning :-[) Hope you like it Best Alex

Hi, Thanks that would be great how much do you ant for them including ship to France? Cheers Alkex

Hi, I'll paypal anyone who can ship an opl3 and two dacs to France... Thanks in Advance Best Alex

HI Folks! I'm a protools user and would love to build a Mackie Hui but as it seems that mios doesn't support the protools mode yet. I am lucky enough to use a mackie control and 2 extenders with protools every day at work. Is there an easy way to crack the protools protocol perhaps by monitoring the midi messages? I could borrow one over the weekend to put under the operating table if anyone could point me a direction to take... Any thoughts? Cheers! Alkex

Merci Thorsten! :)

Hi all, I am working on a funky 14x10 dot matrix display for my next midibox and would like to program a random pattern animation. I am using a matrix of 14 anodes X 10 cathodes and would like to set the anodes high randomly at each Cathode shift, so I need a 1-14 random integer, but can't work the SEQ_CORE_GenRandomNumber... I would greatly appreciate it if someone could guide me through this fonction ... thanks in advance! Best regards Alkex

Hi Mr ModnaR, Nope, it was an old 70s Bontempi toy I picked up for 1.50€ from a charity shop and resprayed ;D I then had 2 Shaeffer panels made to size I would really recommend Bontempi toys for keyboad projects as they are really simple to resolder and contacts are immortal!! Glad you like my Sid Cheers Alkex

Thanks Thorsten, Indeed you where right, I had only set the SR to 0, apparently Pins must be set to 0 also.. Thanks for making my day, AGAIN!! Best regards Alex

Hi there, I have a rather confusing problem. No matter what Pins I attribute to various menu buttons in cs_menu_io_tables.inc, Din pins 0 & 1 of the first shift register always call up the ADSR edit screen, and act as up/down cursors to the REL Value. I am using an encoder, 4 selection buttons and an exe button, all located around shift registers 3 and 4, the first two used for a piano keyboard.I have disabled the up/down cursors in main.asm and set all other menu shortcut pin adresses to sr 0 pin 0 Any suggestions as how to disable pins 0 & 1 ? Thanks in advance Alex

great stuff, thanks!

Hi Folks, I'm planning to build a very compact midibox Sid that will live under the chassis of a standard midi keyboard thus enabling wicked onboard sound, but I wont have space for a cs but would love to benefit from all those great sounding preset patches. how would I code the Dins to change up & down thru presets without use of the cs.. any ideas? Thanks in advance Best Alex

Hi! Sasa, I used http://www.schaeffer-ag.de for the frontpanel. They offer a fun piece of software that you use to "draw" your holes with, great fun! Kokoon, I probably didn't go the easiest way for the patch cables, but being a real beginner, I simply used differant voltages for each output and AIN inputs on the other ends. When you plug a cable across the two points, the AIN value acts as an indicator. Suprisingly, this technique has proved very reliable so far :-\ Thanks for taking a look at my new baby 8) I'd be delighted to answer any further questions!

Hi! Thanks, I'm thrilled you like my design. One important point I have to clarify as I didn't explain properly to Thorsten: The actual Sid core is 100% original Firmware, the whole control surface is a seperate midibox core with custom Mios application that I programmed in ASM from one of the downloadable examples. I'm sure it would just be a matter of copy/paste if anyone would want the ideas in their box! Best regards, Alex

Hi Thorsten, I'm proud to have a bit of my brain built into your excelent SID project :D I use the feature to animated 8 leds in a horizontal "night rider" style to indicate the selected lfo rates. My midibox Sid has a modular approach with software handled patch sockets to simulate connections between voices, lfos, enveloppes etc using patch leads. I still have some bodywork to finish (lcd, pitchbender), and some software handlers to optimize but here's a preview: I really hate having to sit in front of a computer screen to make music, thats why I'm trying to make my midibox synthesizers as independant as possible. This one will eventually have a little amp and speakers so it can be played in a computer-free zone! ;D thanks again for making our beloved projects a reality! Best, Alkex

Thanks Thorsten, now I can have a nice horizontal led visualisation of the lfo rate! ;D The next question is obviously how to grab env 1 and env 2 values? (of coarse, i'll have a try first) Thanks! Best Alex

Hi, I am planning on customizing my midibox sid and would like to generate various midi signals (ccs, midi notes, clock etc) using the 6 lfos that are built into the Mios_Sid application. I therefore need to be able to read the 6 lfo values at any time, convert them to 7bit and send them to tx buffer. Please could someone point me to the 6 variables and need to work on? any ideas on converting them to 7bit (1-127 range)? Thanks in advance! :) Alex

Hi Jidis, I know what you mean about C slipping away! I find it applies to loads of software I use, so much to remember, one month away from the thing and its forgotten! like skiing up and down the learning curve! Anyway, back to the tables buisness, For storing my data, I forgot about tables all together and just use a bankstick with variable as adress pointer That way I have the equivalent of a hard drive with a random access reading head! Best Alex

Hi Thorsten, Looks like stored cc Values in a table of 8-bit entries is the way to go for my project! I'll use a bankstick, should be more than enough to store 12* 50 values!!! Can't wait to get the synth finished, and start playing with it. I'll send you photos as soon as It's finished! Best regards and thanks again for your precious help! Alex

Hi Thorsten! Thanks for your support, I know I should go C but I've just got the hang of the basics of asm so It's not easy to make the change... Anyway, your little example is really helping me out now, only two questions remain: -to store midi CCs using this example, I presume I want to "cut" the 16bit value with into 3 midi bytes using MIOS_HLP_Dec2BCD Right? -You say MyTable is read/writen to and from flash, does this mean I don't need any specific FLASH commands to expect to find the same values after reboot? Enlightenment on those two questions ought to sort me out for good ! I promise I'll make the leap to C on my next project (FM synth) ;) As for the random generator I mentionned, I was just planning on using a couple of noisy AIN pins (maybe with charging/discharging caps of differant values on them and a 555) and filling up a table with consecutive MIOS_AIN_Pin7bitGet commands so It was nothing exciting like your SID RANDOM TOY (which I MUST build some time!) Best regards, and thanks again for your help!

Hi George! thanks for your post, I now understand the basics of table adressing thanks to you! I'll see how far it'll get me ;) I guess next step would be writing to this table... :-\
