Thanks, guys! :-) Just had a listen with notebook speakers - sounds incredibly bad, have to learn how to do proper mastering one day :-D. Many greets, Peter

Hola, it has been a busy year already, but finally found the time to hit the keys, this time focussing on the Alesis Andromeda (only accompanied by the FS1R and the Machinedrum) - copter footage filmed in Fuerteventura - hope you enjoy! :-) http://youtu.be/V_fToovFZ_Q Thanks for watching, listening and your comments! :-) Many greets, Peter

Hi Paul, sorry, can´t help you with non-indented encoders. If you carefully manually remove the detention, it should work. Another failure point (also for Alphas) is that maybe after some use, the encoder case is not firmly closed anymore (metal brackets getting loose) - if there is any kind of wobbling, the encoder wheel will not have good contacts - here is a quick tip: There has been a lot of discussion regarding Bourns encoders quality lately, so i would stay away from them, but I guess there are always production quality differences, even from the same brand :smile:. Many greets! Peter

Have you removed the detention of the encoders? (See ) If you have done it, there might not be enough pressure on the metal lid - you have to bend it towards the encoder wheel afterwards to avoid bad contacts. Mine still run rock solid on the standard MB6582 firmware. Many greets, Peter

Great job and an awesome looking synth! Congratulations! :-) Many greets, Peter

Hi Paul, hm, this is very interesting - my MB6582 Alpha Encoders are rock solid, the best encoders I´ve ever had, even after four years of heavy usage they feel like new, unlike many encoders in commercial synths, the worst are the ones in my Waldorf Micro Q :-). Bought the Alpha Econders @ mouser in 2010 Mouser P/N 318-ENC160F-24P. Many greets, Peter

good price, thanks Altitude! :-) Many greets, Peter

Can you open it up and check for the socketed filter caps? See if they are still in place? Many greets, Peter

It is probably fried - but before you replace it, give the contrast pot a try... Solid black boxes sometimes are caused by wrong LCD contrast. But I fear the short sent it to LCD nirvana :-) Many greets, Peter

Yes, that is how synchronization works with Cubase. Always synchronize with Cubase as MIDI master, it won´t work the other way around. If you want to use the SEQ as a MIDI interface to access your legacy MIDI hardware synths from Cubase, you can configure the MBSEQ MIDI router to forward any MIDI packets received on the virtual USB MIDI ports to your SEQ MIDI OUT1-4 ports. PS: My advice, if you have the MBSEQ, drop Cubase :-) Many greets and enjoy! Peter

Good suggestions! What also really helps to remove motor noise is a LC filter (inductivity, capacitance) - just wind a few turns of cable through a ferrite core, and attach a big electolyte (e.g. 2200uf) and a small ceramic (e.g. 100nf) capacitor. Here is a small howto: http://www.fpvuk.org/how-tos/lc-filters/ Only connect the fan after the LC-filter, i´d bet you see a massive improvement. Many greets, Peter

Ok, those 6581 (12V powered) SIDs will run hotter than the 8580/6582, maybe have an eye on the surface temperature of your heatsinks, if you remove the fan and the fan grill on the backside you can measure with an inexpensive infrared thermometer after half an hour of usage without disassembling the unit :-). Bye, Peter

If you´re using 8580/6582 SIDs, a fan might not be necessary - also you can passively cool your SIDs with heatsinks. No problem on my side so far with that solution :) Many greets, Peter

My left small toe somehow tells me, that MIDIbox would have switched to the competitor anyways, but at least now we can blame the original manufacturer :-D. / what on earth were they smoking to make such a redesign decision? :-)

Hi Smidirin, Great, that you´ve got it all soldered up, and i am glad, Ilmenator created that fine PCB and TK improved the code! This would be the relevant config section in the MBSEQ_V4.HW file - don´t change the 16x4 BLM section, but this one instead: ################################################## # Optional LED Track Position Display # See also http://www.midibox.org/dokuwiki/doku.php?id=tpd_pcb ################################################## # set to 1 or 2 to enable the relative track position display # 0: TPD disabled # 1: TPD enabled - columns are cathodes, rows are anodes # 2: TPD enabled - columns are anodes, rows are cathodes TPD_ENABLED 0 # define the DOUT shift register to which the columns are connected (0=disabled) TPD_COLUMNS_SR_L 0 # for a 16x16 TPD: define the SR to which the right columns are connected (0=disabled, use only 8x8 TPD) TPD_COLUMNS_SR_R 0 # define the DOUT shift register to which the green LED rows are connected (0=disabled) TPD_ROWS_SR_GREEN_L 0 # define the DOUT shift register to which the right green LED rows are connected (0=disabled, use only 8x8 TPD) TPD_ROWS_SR_GREEN_R 0 # define the DOUT shift register to which the red LED rows are connected (0=disabled) TPD_ROWS_SR_RED_L 0 # define the DOUT shift register to which the right red LED rows are connected (0=disabled, use only 8x8 TPD) TPD_ROWS_SR_RED_R 0 Also, have a look at the "optional bpm digits" and "optional step display" sections and modify those. The newest MBSEQ V4 hardware config file is available for download here: http://svnmios.midibox.org/listing.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fsequencers%2Fmidibox_seq_v4%2Fhwcfg%2Fwilba%2F Edit: there seems to be a slight problem web downloading files with the given svn repository link above - never mind, you could just click on the file, mark its contents and copy&paste it to your favourite editor. Many greets, Peter

Hmm, Could it have been a cheap clone? Which shop did you order it from? Many greets, Peter

Thanks, Shuriken! Nah, it is not really dangerous, there was a local hill nearby, which is quite high, so the perceived altitude seems higher... Also, we fly with a spotter, that makes sure the airspace is unpopulated by other flying objects (like low flying propeller machines or helicopters) and that can take over in case of a video link failure (which is a live feed to your video goggles, the recorded images are from onboard recorders). Additionally, there is an autopilot on board, which returns the unit back home safely, in case of radio link loss, video link loss, motor power loss (sailing home) or when the pilot faints :-). The unsafe looking scene around the houses was a quickly flown multicopter course in the backcountry, with people watching the (non public) road, so that no incoming pedestrians can get surprised. The flying wing weighs only 700 grams and is built out of very soft foam material, so even if it went down uncontrollably in a 45° degree angle (the airfoil drag will prevent steeper descents) from an arbitrary height, no big damage would occur, as the max ground impact speed would not exceed 60-70km/h. Of course, the hobby is also insured and you pay some bucks per year to cover for these worst case scenarios, but you´re right, it is important to be responsible and not take any risks at all! Many greets, Peter

Thank you both! :clover: Unfortunately, the moon was out of range :-) Hehe, Many greets and thanks for everything! Peter

Hola, a new track live from the studio using the MIDIbox SEQ, an Alesis A6 and the MB6582 (and some aerial footage :-)) I tried to re-record this one in cubase, but it would sound far worse than the original take, so the original it is :-). Needless to say, i am really thankful for the MIDIbox hardware - fantastic and so much better than software for me :-) Many greets and thanks for watching and listening! Peter

Hola Pete, those 780X switcher replacements are very usable imho - especially if they only power digital circuitry. But many have used it for analog stuff - if the switching frequency is high enough (> audible range) and you filtered with a few caps and maybe an inductor for scenarios, where there are sudden current changes (not necessary in many applications). Here is another unit, that i´ve used personally and that works great: http://uk.farnell.com/tracopower/tsr-1-2450/converter-dc-dc-5v-1a-sip/dp/1696320 Many greets, Peter (with the same pre and surname as i was told by SmashTv ;-))

You´re welcome! Nearly everything should be controllable via MIDI - look here: http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fsynthesizers%2Fmidibox_sid_v2%2Fdoc%2Fmbsidv2_parameter_chart.txt http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fsynthesizers%2Fmidibox_sid_v2%2Fdoc%2Fmbsidv2_cc_chart.txt http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fsynthesizers%2Fmidibox_sid_v2%2Fdoc%2Fmbsidv2_sysex_implementation.txt Many greets and have fun! Peter

Hola and welcome to the forums, you´re in the right place and the in the right time, the MIDIbox line of SID synths beats any other SID synth on this planet :-). A suggestion, if you are into soldering and want an expandable unit, consider the MB6582 - you can start with 2 SIDs in the beginning and grow up to 8 SIDs, and it sounds awesome! Here is a (self advertisement :-)) small walkthrough of how to build the control surface: If you have any questions, there are many helpful people around here :smile: Many greets, and enjoy! Peter

moodawg - ok, confusion here :-) I thought you were proposing to implement the full RTP functionality on the same MIOS32 core as the SEQ (and using the ethernet port of the LPC17 for example) - that would not work. Using the existing KissBox add-on core (connected via SPI) would work, of course and add MIDI RTP support to all new MIDIboxes. To save some $$$, someone with lots of time at hand could implement the RTP MIDI protocol on a cheaper add-on core, connected identically via SPI. Many greets, Peter
