Hello ! Ok, so tested the AOUT_NG, i have the right voltage int IC3, and IC4, launched the SEQV4, but i can't mesure something like 5V at the output, i have 0v, nothing else...

Yep, the Quad IIc, include all the needed parts, as well for the BLM connector, but i don,t understand where to connect the 10pin connector on the LPC17. I tried to sequence the shruthi from the Quad IIC, and it worked as well. What kind of Case are you doing ? 19in rack ? i'm acually work on a tilled case, which must fit with the 19'' frontpanel (It's quite hard to find a rack which can be used with the SEQV4, because of the little place on the top and side of the pcb.

What do you mean by ''Extra-parts'' ? I builded it from smashTV pcb, completed the PCB, it looks good. Also, builded the AOUT_NG yesterday, the led is on, i have to check, and calibre it today !

Quad IIC working, now, let work on the AOUT_NG :purple:

Works perfectly :D Now, i have to connect a quad IIc, and a Aout_Ng ! I come back ! Thanks guyz ! Bye !

if i leave everything, no problem at all ? i have just to connect to J2 ? bo jumper or something to do ?

Hello there some news here, and some questions ! I try to use an external PSU, but i have a question, mine is +12/+5/0/-12 (Iwant to use a Aout NG) The problem is : On the LPC17 Page, it say on J1 : Optional connection to a powersupply unit (PSU). A 7V-10V transformer, or a wall adapter could be used. At least 500 mA is recommended, especially if a backlit display is connected. AC or DC doesn't matter, since the rectifier behind J1 converts to DC anyhow. Also the polarity has not to be taken into account. I thought I could power the SEQ V4 with 5V, but it looks like not, and it need 7-10V. I can see on J2, that it can be used as +5V input to power the core. Can i power all the SEQV4, including, everything needed, BLM, backlight screens,... via J2 ? If not could i use a step up voltage regulator, to come from 5V to 9V without any problem ? Something like that ? : http://www.pololu.com/product/2116 or : http://www.ebay.com/itm/2-in-1-Step-up-Step-down-Adjustable-Voltage-Module-DC-5V-9V-to-12V-12V-to-9V-5V-/271266514245?pt=LH_DefaultDomain_0&hash=item3f28be8545 Thanks for your answer. Bye !

I have another question about the PSU for a SEQ V4, Particulary about the switching power supply. I know people of mutable instruments building euroracks, are using the mean well T-60B, without any problem. What about power the SEQV4, with theses kind of PSU ? Maybe something like this : Mean well T-40B : http://www.meanwell.com/search/T-40/default.htm (no more avialable :sad: ) With a switching frequency over 40kHz, i think there won,t be an problem ? (maybe i'm wrong) With this one, the switching frequency is 70kHz +/-10%, so what about this one ? 3.5A for the 5V, enough for the SEQV4, AOUT_NG, and a BLM. Here is some risk to use it first only with the SEQV4 ? (I mean, can i damage something by having 3.5A) Thanks for your answer ! Bye :smile:

If your going to go in MIdiboxes, you will have to search a lot of things, and read, read, re-read, an d when you will have integrated all the midibox things, you will have to re read again ! Check the Ucapps site, all the things are explained there ! Have fun !

Working for me too ! Thanks altitude for the tip ! Bye :rofl:

Problem solved, after searching everywhere for like 3 hours, SEQV4 is ok ! (But i'M not sure i rememeber everything i did :D Bye !

Hello, I have some problems : I loaded the PROJECT.BIN, it loaded correctly, when i boot it, the led fade 3 times, and light after. So i tried to load the last SEQV4 firmware, but can't load it ! connect it via the LPC17 USB, but if i open the MIOS studio, impossbile to see the interface... What to try, i'm really lost in all the software things..... :pinch: Bye

What the fuck is all this stuff ? Only controller ? Some videos to see how it's used ?

as i said, i would take one, but my tr 9090 is not build actually so if no one want it, i would take this !

Any news ?

Milky way at home !

Maybe we can think about an encoder bulk from one manufacturer, and order different Models, like with/without switch, illuminated or not, D-shat or not... I'm in ! And also pots, for other projects,

I need an older installer for windows ! Sems that i can't find freeRTOS on the new version. Edit : Just found this : http://www.lpcware.com/lpcxpresso/downloads/older

Oh yeah that looks really good in milky ! ok more knobs needed.... Do you think with a more ''normal'' led (1000mcd seems to be a high liminosity) it will me visible ? Thansk for that test ! Bye

is the milky a white translucent, or just an opaque (opac? opak ?) ?

aucun problème de mon coté ! arrangeant et tout !

I'm in for a pcb too !
