  1. Wouldn't be surprised if one Core could handle all the SIDs. These beasts are quite different type of league... Btw, here's another post by TK that popped on my mind: http://www.midibox.org/forum/index.php/topic,12632.msg106231.html#msg106231 I don't know if 32-bits give any unconditional advantage over PIC (MBSID is just great thing already!), so it's also something up to the end user to decide. But sure it gives alot of freedom for new features (although the original HW design may be also limiting this but dunno, the STM32 does not have external bus anyway). I think the biggest down sides in 32-bit designs are the fine-pitch SMD cases and somewhat more complicated development tools. But nothing that one couldn't survive!
  2. Well, I think I should let TK speak for himself (I rarely take part on any conversation in here anyway so who am I to reply?), but according to this post there will be another version at some point: http://www.midibox.org/forum/index.php/topic,12673.msg106686.html#msg106686 However TK probably wants to say something about this as well :) That said something I can speak about: I decided to go for MB-6582. My original intention was to make a version of my own with some modifications, but the ready made PCB is just priced fair enough so I thought to save my precious time for another time and go with a known good design. Plus it's alot less hassle compared to building the thing from a separate modules - again saves my precious time. However I'm still thinking about implementing part of the mods I've had in my mind (to try them out if they make any sense). When/if there will be MBSID V3, I will start from scratch and re-make the synth with the new design. I'm actually all thrilled about the STM32 core (wonder if I could collaborate somehow).
  3. This is sweet, nice work! It appears that I've been away for far long time as there seems to be so much new to explore! Will really look forward on this, maybe have to finally put together SEQ of my own... But aren't those 32-bit micros just sweet as well? We have found that most of the recent projects at work are also based on similar chips (ARM7) as today the price is almost the same as 8-bit devices and you are having alot less limitations to deal with. It's not until higher production volumes when you really have to pay some attention on the micro to cut down the costs. I'm also happy that I'll be able to use the same tools with the MBHP_CORE_STM32 :D
  4. Not my call, but I'll reply to this anyway :P We are using Winstar's 240*128 LCD modules equipped with T6963C at work. We can show values etc from the PC on device's display and the update times are about 10-15 milliseconds (not full screen though), where most of the lag comes from the IIC communication (the inner communication of the device). It's not even the T6963 that is slowind down the update speed - the bottle neck for speed would be the crystals of the display not changing rapidly enough! So this just for an example out from MBHP, maybe the design of IOWarrior is poor (haven't read the specs). Btw, TK have done benchmarking on different LCD's in past, maybe this reveals something about performance?: http://www.midibox.org/forum/index.php?topic=2169.0 Plus we never should forget that if big part of the "intelligence" of the device lays in windows application (is this where the controlling of the lcd module is being done?), it never can be too fast - nor precise.. ::)
  5. Actually it may take only couple of days to find out the truth that you are needing the thing you just thought you'd ever need.. On the other hand, without going thru all the forgotten stuff piled up you necessary wouldn't have remembered that thing anyway :) Throwing away old "junk" is always hard thing to do.. It's been few months by now since I moved up to my current location and there's still few boxes left that I don't know should I trash'em or not.. *sigh* Some "anew found" treasures lies on my desk now, like some more parts for FM synth, MB controlled analogue synth.. Just needing time!
  6. For heating, eh? After moving up to my current location I stuffed up all the comps (including couple old 19" servers) into one single room. Soon I found out that I don't need to keep the heating on at all in that room. Actually the room temperature was higher on that room than in any other in the house. So to cut down the less or more massive housekeeping costs I got rid of most computer hardware.. ...but can't live without this! Things like OpenWrt and some cheap wireless router does the dirty job fine enough in home use and allows plenty of flexibility. Actually having a "better" firewall hardware was no good anyways if you got flooded with a pipe large enought to fill up yours...
  7. Well, you'll just need to tag some MB hardware on it and it'll be one of the finest piece of MIDI hardware ever ;D Actually, after bit of googlishm it seems that several modded individuals of this little beast does actually exist...
  8. Nice find! It is being funny that it actually took a little bit of an effort to find couple of old soundcards to get these little chips. First I thought that these shouldn't be hard to find but.. This could be a good source for FM syth parts if someone just wants to arrange up things some :) For some reason though there seems not to be quite many of Midibox FM synth builders? Hmm..
  9. Greetings, Yes, You are still able to save the chip indeed! I've done this couple of times in past as well. The plastic cover of the IC is quite soft and you can try to remove it as much as is being necessary to get something soldered to the pin. A file may be ok for this job but I did this with dremel - quick job and more nice looking result IMHO. Just need to be careful.. Good luck!
  10. Maybe I have to give it a try as well! I know there are synthesizers with similar joystick implemented but I have never had chance to use one. Without knowing any better I've always been just happy with all these knobs and clutches. ;D However I think that top priority thing is to get everything into box now instead of my desk. I just haven't made up my mind on certain decisions and this could be one more thing to try at. Regards, Petri
  11. Quite nice looking thing, good job! The joystick is neat idea but how useful is it? It appears that there are few of these implementations done in past as well. Regards, Petri
  12. Bingo! This is the very reason why I tend to recommend solder wick or similar stuff for desoldering instead of using desoldering pump if you are not being experienced in soldering. Applying a lot (well, too much) of heat will cause the pads to detach from PCB, especially if there is any force applied on pad. Yes, you can get the pads off with solder wick as well if you start rubbing it against the joint, but in my opinion it is still safer way that using a pump. Thus a trick for using solder wick that may not be so obvious: Solder the tip of the wick strip. May sound stupid, but the wick works best when there's some solder and extra resin in it. Apply only gentle force over the wick and joint and let the wick do the magic. Never start to stir around the soldering iron! If you are able to control the temperature of your soldering iron you may also increase the temperature little for this operation. Otherwise the temperature may not spread wide enough. Just my 2 cents. Regards, Petri
  13. Hmm, been wondering if it would make any sense to make external filter unit for SID. Having few filters in it, maybe even totally different of types, and then use whatever you want via filter matrix kind of coupling. It wouldn't be too hard to make with an analog switch matrix IC's although they are not available in every electronics shops and therefore being quite expensive. Though it would be nice to have more analog outs to control them. Then again could take some DSP chip and begin to program some earth shattering filters..! I think I still have one Freescale chip somewhere in my junkbox. Hmm.. :-) It's just.. Where do you guys get all of your time you need for building all this stuff? ::) Regards, Petri
  14. Most interesting. So would this be traditional hardware based bending or is there a way to do the trick inside software? This truly would give more unique sounds out of the SID box! :-) Regards, Petri
  15. Hmm, well I doubt that this would be an unnameized and modified copy of Thorsten's MIDIbox and MIOS by any means. Similarity exists but the idea behind this device is hardly that unique though. It is however quite possible that the inventors of this box have taken a look to MIDIbox as well - and who knows how many other projects and existing products around (eg. Doepfer Musikelektronik's stuff). I suppose MIDIboxers are free to absorb the ideas from the Mazer construction as well, which looks like pretty neat I think. Regards, Petri
