Cool, looking forward to it ..

That works! I was almost there (run a script with a button), but was using trigger instead of send... Thanks!! btw, will timed events be supported sometime in the future? Not that it's super important, just curious... Lars

Hello, I’m thinking about a solution for the following scenario: I have an encoder with an integrated switch. With this encoder I want to send program change commands, but in the following way: - when I move the encoder I scroll through a list of programs (via NGL-file) which are displayed on a LCD, but the encoder actually DOES NOT send the prog-change command yet - when I found the right program in the list I press the switch and the prog-change command gets send out Is that possible with MB NG? I’ve read through the manual but couldn’t find a proper solution yet, but maybe I’m just too dumb… Icing on the cake would be if I scroll through the list but don’t press the switch, the value on the display jumps back to the current value after a few seconds. Cheers Lars

Ah, ok, I see. Not a problem, a have a few 74HC165 in the drawer anyway.. Cheers Lars

Just wanna confirm that these 3M sockets work really well... Thanks again sneak-thief

Hi, is it possible to connect encoders directly to a STM32F4-CORE board running MB-NG without the need for an additional DINX? I know the SCS uses port J10A, so it would be nice if we could either re-configure that port for "normal" encoders/buttons (non-SCS), or if we could use J10B for that purpose. Lars

And what's even more awesome: me and sneakthief just discovered we live in the same street and are almost neighbors since eight years... :D :D

You guys are awesome!!!!!! Thank you! sneakthief, that'll be perfect, I'm in Friedrichshain, too! I'll send you a PM now...

Hey, I got my STM32F4 core pcb from smash and almost finished it except the sd card socket. In are pictures of two different sockets. I think I found the 3M one at mouser (mouser-no. 517-SD-RSMT-2-MQ). - does anyone know what brand the other one is? - does anyone know where to get either one of those in germany (or europe) apart from mouser? their shipping cost is 20 euros… - can I still connect a sd card socket via J16 if I don’t use the „internal“ one? Cheers Lars

Works perfectly on my side here. Thanks Norbim!!!!!!

Thanks Thorsten. I connected my TDA1543 board (built one according to mbhp_i2s_tda1543.pdf) like this: STM32DISCOVERY -> TDA1543 PA4 (LRCK) -> Pin#2 (WS) PB9 (SDA) -> Pin#3 (DAT) PC10 (SCLK) -> Pin#1 (SCK) ...and 5V, GND and audio outputs of course. but I couldn't get any sound out of it. Don't know if this is supposed to work like that. I mean connecting a second DAC in parallel..

Thanks for your feedback, guys! Yep, a mellotron sample ;) You're right, it is definitely a usable signal, for sure (though I have to say when you play/change chords it's much more obvious than in my example). I just wanted to make sure that there's nothing wrong with my setup, and I still wonder why it's only in the release phase while the rest of the sample plays back fine.. It's just a wild guess but maybe we hear some kind of bit-crushing when the sample fades out (saying: volume gets turned down digitally and the bit-resolution gets lower). I remember the audio-output from my macbook makes all kinds of weird noises when set to a low volume. However I know It's not high-end DAC but I find it quite ok, and it comes for free with the STM32, so I won't complain :shifty: BTW does anybody know if we are still able to connect an external DAC to the STM32F4? On the new MBHP_CORE_STM32F4 the pins should be at J10B but I have no idea how to active that.

Here's a small sample I did with two different release times. You can hear the distorted tail of the samples. Anybody else having that problem with the SD Card Player? sdcardsampler_dist.wav

It's working now! But I noticed a strange behavior with the release phase of a sample: I always get a crispy/crackling sound when I release a key, no matter what I set the release parameter to. With no release phase (value 0) I just get a short klick (which I think is normal), but with longer release times (say up to 1000) the whole release phase of a sample is distorted/crackling. When I press a key till the sample ends everything is fine btw. I already tried different samples and different volumes, but the problem remains. I tried a LPC17 core with the sample player app a few months ago, and as far as I can remember there wasn't such a problem, but I'm not 100% sure. Could that be STM32F4-related? I could try my external DAC (TDA1543 based) that I used with the LPC17 if there is a way to connect that to the STM32F4.

Hey, I have a problem getting the Sample Player to work with the new STM32F4. I uploaded the project.hex and connected my sdcard with some samples, and they seem to load fine, BUT I can't hear anything?! When I connect my headphones I can hear a bit of white noise after the application is loaded, so that tells me that the audio out is (somehow?) initialized. My hardware config: - just the STM32F4-Discovery (no MBHP_CORE_STM32F4) with the additional jumper cable for 5V and an sdcard-reader directly connected - I tried two different sdcards, one 4gb with FAT32 (I know I should use FAT16) and one 4GB with 2x2GB FAT16 partitions - I know that these samples worked with a LPC17 based core - I tried uploading MB_NG and it also seems to work fine, also with the sdcard file browser - I connected the Audio-Out to headphones and to a mixer line-input as well, still nothing - according to MIOS Studio terminal output, everything is configured and loads up fine (see screenshots) What I am doing wrong? (If anybody wants to try my sdcard-files, they are here)
