you paid $16 :)

i grabbed the demo of audiorealism bassline 2, and unfortunately i don't think the step parameters are exposed to live. i did a dump of what's available, and here it is: [696172.950] DEBUG: Device On [696172.961] DEBUG: Tune [696172.972] DEBUG: Cutoff [696172.984] DEBUG: Resonance [696172.994] DEBUG: Env.mod [696173.006] DEBUG: Decay [696173.017] DEBUG: Accent [696173.028] DEBUG: Drive [696173.040] DEBUG: Distortion [696173.051] DEBUG: Volume [696173.063] DEBUG: Reserved [696173.074] DEBUG: Waveform [696173.091] DEBUG: DistortionType [696173.107] DEBUG: HighpassFilter i looked into the parameter called "reserved" just to make sure, changing it doesn't seem to do anything. sorry to get your hopes up. ultra

you could likely get the feedback you want with liveapi. this requires coding your own script in python which you load like any other control surface. it's not the easiest thing to do if you don't know python or any other OOP language, but it's worth learning because using liveapi has countless applications. whether or not it's possible depends on if those step functions are exposed to live. they probably are if they're midi assignable.

what host are you using?

i would install a midi loopback (such as loopbe on windows) and route the software's output to midi-ox. ultra

congrats on the midibox sid, igi. looks really nice. is that a front panel express panel?

awesome

congrats gtxdude. nice seq!

cool button, but the price would add up pretty fast.

somehow i left out the code where it's assigning the mask. that's done by note numbers.

i've been trying to figure out how the blm_scalar driver works (mios32\trunk\modules\blm_scalar.c) and adapt it to my own needs. my pcb is a control surface with the two scalar circuits built in, and it just all connects via one ribbon cable to j8/j9. i've checked my schematic for problems several times, and have done continuity tests on the boards, and i'm 99% sure there aren't any problems with it (i did have to fix a couple). i've figured a few things out, but so far, i'm having a couple problems. the buttons: only the buttons on the first scalar circuit give me any response from mios32. they work well, but there's no indication that the buttons on the second scalar circuit are working at all. i've added the following line to mios32_config.h: #define BLM_SCALAR_NUM_MODULES 2 when i insert debugging code into the blm_scalar driver, i can see that 2 is what it's set at. but still, no buttons on the second scalar circuit respond. the leds: my led issue might not be as straightforward. i put the following line in mios32_config.h: #define BLM_SCALAR_NUM_COLOURS 2 i have 2 color (red, green, orange) leds, so i assume that's the correct setting. i took the code from the blm_scalar controller example (mios32\trunk\apps\controllers\blm_scalar\app.c) and modified it so that my keyboard's knobs change the mod and row values being sent in, and mask is defined by which key is played. it modifies the following line of code from the app: blm_scalar_led[led_mod_ix][led_row_ix][0] &= ~led_mask; of course, i also have the variations of it to turn on/off and set the color. i'm using the masks 1, 2, 4, 8, 16, 32, 64, and 128 for the keys. most of the leds do light up, and the color is changed with velocity. so most of the board is working fine. a couple of problems though: the leds that should light up with mask 1 don't do anything. i've double checked the circuit and everything seems fine. also, i have gotten them to turn on by using loops and BLM_SCALAR_DOUT_PinSet to turn on as many pins as i can. changing different led_mod_ix values doesn't do anything (for any of these, it's 0 for all) and changing row does indeed change row. but using the mask 1 doesn't light them up for some reason. the second problem is with the second scalar circuit. i change mios32_config.h to have the following line: #define BLM_SCALAR_NUM_MODULES 2 now the leds that were working properly are very dim and flickery. and also, i can't get the leds in the second circuit to light up (i'm not sure if i need different masks or mod_ix or row_ix). however, i did get some of them to light up when using the loops and BLM_SCALAR_DOUT_PinSet. and if i recall, all leds had the proper brightness. otherwise, what does work, works great. any help with these problems would be greatly appreciated. sorry if this is a bit of a cross-post, but i've since figured a lot more out about the problems i'm having. ultra here is the code i'm trying to work with so far: /* * ========================================================================== * * Copyright (C) 2011 Drew Meyer (drew@sub-version.net) * Licensed for personal non-commercial use only. * All other rights reserved. * * ========================================================================== */ ///////////////////////////////////////////////////////////////////////////// // Include files ///////////////////////////////////////////////////////////////////////////// #include <mios32.h> #include "app.h" #include "mbltrigger.h" #include "mblblm.h" #include <blm_scalar.h> #include <FreeRTOS.h> #include <task.h> #include <queue.h> ///////////////////////////////////////////////////////////////////////////// // Local definitions ///////////////////////////////////////////////////////////////////////////// #define PRIORITY_TASK_BLM_CHECK ( tskIDLE_PRIORITY + 2 ) ///////////////////////////////////////////////////////////////////////////// // Prototypes ///////////////////////////////////////////////////////////////////////////// static void TASK_BLM_Check(void *pvParameters);
