As TK said, the easiest way is to create a script that contains exactly what you would type on the command line to do all the things you need to do. It is called "shell script" and contains just a list of commands, which are executed one by one. This works on any platform and always executes all commands given, no matter what. If your university project demands for a "normal" makefile, you should really go the full way and read into http://www.gnu.org/s...anual/make.html An easy way would be to find any open source project, that has a makefile and does what you need, and just copy and alter it. On the other hand, make is really not so difficult, it is just a list of "what to build: how to build it" statements. So, what is the difference between make and the shell script? Make will check for anything already present, which needs not to be made again, whereas the script will always build everything, which really should not be a problem for a small project.

Heheh, thx guys, made me smile :smile:

Thanks a lot for the length restore after clear! Sounds good with the unified copy behaviour to SD! Many greets! Peter

Hi, willst Du es umsetzen, würde ich Dir das MIDIO128 V3 Projekt empfehlen -> http://ucapps.de/midio128.html für jeweils 32 Taster brauchst Du ein DINX4 Modul (es gehen auch mehr mit einem Modul, dann musst Du jedoch eine Button-Matrix basteln) Dennoch hat Ilmenator schon Recht, der SEQV4 kann vermutlich alles was Du willst "von sich aus" und Du erzielst eine bessere Integration... da aber beide Projekte auf dem LPC17 und den DIN (SEQ V4 auch DOUT) Modulen aufbauen, kannst Du jederzeit das MIDIO Projekt zu einem vollen SEQ upgraden und den Doepfer auf ebay weiterverkaufen :-) Ciao, Peter

Yes, it should be possible, am planning on using a step up converter with two AA batteries - providing 5V @ 250ma, which may be sufficient. There are some really cheap "china" solutions out there, you can find them when searching for the term "usb emergency charger". Of course, there are also dedicated chips for this, if you want to build it on your own - i´ve failed miserably @ my first attempts :-) Other solutions would require more batteries and voltage down-regulation. Greets, Peter

It seems to be a common resistor network, if you compare your measurements with Tim´s picture, so it looks ok.

Hi Flex, lets say you configure/develop it like this: pushed state = fixed 10 units per tick = parameter 0-127 in 13 ticks or 13x15 = 195 degrees reached. unpushed: fixed 1 unit per tick = very hi-res unaccellerated fine tuning possible. both states are without acceleration! That results in a predictable behaviour not depending on rotation speed and current moon phase :-) Dunno how AKAI does it, but they either have higher-resolution encoders (don´t know what is available?) or they use accelleration, or they don´t allow real finetuning (e.g. minimum change of 2 units per tick). I also got the pushable alps stec12e encoders in the midibox seq v4 and they work really nice! Greets, Peter

Yes, unfortunately the Commodore brand changes owners like aged cheerleaders :)

Thanks flip! Sorry for the mad pianist style, will go back to the synths next time and prepare better - this demo really was very quickly done :) Greets, Peter

Hi there, a good choice imho is the "press to accelerate" function originally brought to us by the elektron mds - gives a very controllable behaviour - very high-res when not pressed (feels better than a potentiometer), and quick parameter changes when pressed. The MBSEQV4 supports this since a while, and you can implement this behaviour for yourself in another MIDIbox project. Highly recommended. If you combine that feature with a LED ring, you have the ultimate user interface element :-). Best regards! Peter

Tim, thanks for all your hard work and exceptionally quick shipping! For example, I am not aware of any overseas shop, that has set up a "low value" order page. Your services can easily compete with the big shops, please keep it up exactly as it is! There will always be unsatisfied people, everywhere. Many greetings! Peter

Thanks, cit! Here is the promised quick test-drive of the ´lite - totally different than your demo, though :) Many greetings! Peter

Hi, just did a quick test-drive of the MBSEQV4L - a great live sequencer! This time, it lends me two more virtual hands on the classical midified piano, everything is improvised, so please bear with me :) No SIDs and a bit dark this time, it is always like this in winter... :-) Many greetings and thanks to everyone involved with the ´lite! Peter

Thanks for the information! It starts about now :) Will give it a maximum of 50 tries, albeit I fear a lot of crowdsourced people are at it :) Greets, Peter

Thanks to all :-) Nao, lets do some more step-up-converter burning :) Greets, Peter

Yes, it can also be on the baseboard - I had a problem with malfunctioning switches and leds on the seq v4 lite yesterday and was sure it was due to a problem on the cs - but no, it was a bad solder point on the core board. First time it happened to me, the solder point looked perfectly good, even under a magnifying glass! Just continue to trace on the baseboard, until you see different behaviour to a working switch - somewhere there must be the problem. Greets and good luck! Peter

Yes, the SMD LEDs are very nice on that small device. It looks so fragile, yet it is so powerful :clover: Thanks again for that fantastic piece of music equipment! Greets, Peter

Hola, The white PCB looks so yummy, that I did not want to hide it :-) Just had some fun soldering a few SMD LEDs and sawing two leftover pieces of ebony wood. The transistors and the resistors were soldered to the backside of the frontpanel PCB, because I would not like them on top. Also, I am playing with the idea of powering it with two AA batteries, using a voltage step-up converter - I successfully already burned two of those converters while experimenting :-) The ´lite is a real great live seq, just had a first testing session @ the midified piano, and it was very nice - hoping for a demo soon! The tactile switches are "softtouch" ALPS SMD switches, available for 6€ per 100 pieces somewhere on ebay, they have a very nice feeling and do fit perfectly when mounted diagonally, which adds to the chaotic look :-) The SMD LEDs are green and orange, which I also had leftover - they are very easy to solder on the existing LED pads. Thanks to everyone involved in this project, CD for the initial idea + pcb layouting, TK for the realization, SmashTV for production and fast shipping! Have lots of fun with your lites, this one is official #76 :-) Best regards, Peter

Hi Thorsten, Is it possible that "clear" also resets/changes the tracklength since a few versions? Observed on the lite and on the big SEQ V4... it would be great to revert to the old behaviour, if possible (of course, only if I did not miss anything essential here :-)) Also, but this is probably not easily possible, would you think that "UNDO" could revert to the last track notes, just like it was before the previous live recording "session"? Probably not, because another track buffer would be required, but if it would be possible, this would be a total killer feature and great for trying out variations with just a single button press to revert :-) (I know, it is possible by pasting the track from the track copy buffer on the SD card on the big seq, but on the lite ? :-)) EDIT: Sorry, just installed the SD card on the Lite and then it works very nicely with copy + paste, all is good :clover: (in fact, it was documented, all blame on me :-)). Btw: the lite rocks massively! :-) - Will put on a few pictures and hopefully a demo soon :-) Thanks for that wonderful piece of new hardware :) Best regards! Peter

Hi Tim, have you checked the wiring? I tried it out on a breadboard first, and had to correct a few assumptions, e.g. it may be that you accidentally have inverse digit order or inverse dout pin wiring... Wrongly lit segments was exactly what I experienced too, at first... If nothing helps, i am currently building the lite, too, and could test with a dout module in a few days from now.... Just wanted to reassure everybody, that the BPM + Step Display and the TPD works fine in the big Seq V4. Greets, Peter

Hi, am building a "slanted" version of it, the minimum space you need is 14mm above J15A and 30mm for the MIDI jacks (that is because the SEQV4L connectors are directly above them). As Imp wrote, if you solder directly to the SEQV4L PCB, you could save a little bit of vertical space here, i´d say ca 7mm... Also, 14mm @J15A, this is with the cables pressed very flat, so it would be better to add a few mm :) Have lots of fun building it :-) Greets, Peter
