  6. Seq V4 Gate Outputs - Gate, Slide, Accent like in SID V2?

    in MIDIbox SEQ

    Posted

    from  SEQ_CV_SendPackage in  core/seq_cv.c: 

    // if channel 1..8: set only note value on CV OUT #1..8, triggers Gate #1..8
// if channel 9..12: set note/velocity on each pin pair (CV OUT #1/2, #3/4, #5/6, #7/8), triggers Gate #1+2, #3+4, #5+6, #7+8
// if channel 13..15: set velocity/note on each pin pair (CV OUT #1/2, #3/4, #5/6), triggers Gate #1+2, #3+4, #5+6
// if channel 16: trigger the extension pins (DOUT)

    This is entirely new to me! Is the pairing feature only available via the actual tracks 9-15 on the Seq?

    So this way there already is a velocity feature implemented, which is much more desirable than accent on/off anyway!

    But instead of duplicating the gate signal across the paired pins, #1/2, #3/4, #5/6, #7/8, couldn't the second pin of each pair go high when velocity exceeds 100? Which would naturally also happen when the accent trig is active?

    This way there'd be note, velocity, accent, all in one flexible package... Or am I misunderstanding something?

  8. Seq V4 Gate Outputs - Gate, Slide, Accent like in SID V2?

    Apologies if this has been explained before and I simply didn't find it.

    See title. Correct me if I'm wrong: the SID V2 engine seems to offer the option to directly forward various information to the "gate" output pins, including gate, slide, and accent information (when using the bassline or drum mode)
    Is the same possible with the SEQ V4? Or are the gate outputs (I will be using a dedicated DOUT shift register) somehow hard-wired to pair up with their respective CV channels? Like gate 1 always goes with CV 1 (and outputs the gates of the track that CV 1 is assigned to)

  9. MIDIbox CV V2 Concept

    in MIDIfication

    Posted

    I've been testing the CV V2 app on my Core LPC17 and I'm using the standard SCS. Is it still the case that no sequencer features are available via the SCS? Are they only available from the lemur/ipad/touch screen? Or is the LPC17 firmware not updated anymore, i.e. I'd have to get a STM32F4 to get access to more and/or newer features? Thanks

  11. Page scroll with 4x20 LCD

    in MIDIbox SID

    Posted

    I'm one of those guys with a 4x20 LCD and 10 buttons  on their SID v2 (5 above, 5 below). Menu scrolling is great, just not perfectly intuitive. Right now I am diving into the code and trying  to make the necessary changes to make the menu scroll 5 (or even 10) parameters at a time (which equals one full line, or a full page). I just feel like this is more intuitive than the current way of scrolling through the parameters one at a time. Even, say, on a 2-line LCD it doesn't feel optimal for me because it would feel better to know that, i.e. I can find OSC always at the first entry either in line 1&2 or 3&4, instead of having the positions just floating around arbitrarily

    Long story short, I'd like the menu scrolling to scroll 5 parameters at a time instead of 1.

    This is the passage I believe I need to edit: (found in /src/cs_menu.inc) 

    ;; --------------------------------------------------------------------------
;;  called by cs_menu_enc.inc when the menu pos should be updated
;;  item in CS_MENU_PARAMETER_L
;; --------------------------------------------------------------------------
CS_MENU_MenuPosUpdate
	;; copy result to cursor pos and request display update
	movf	CS_MENU_PARAMETER_L, W
	andlw	0x3f
	movwf	CS_MENU_CURSOR_POS

	;; set page offset directly
	movwf	CS_MENU_PAGE_OFFSET

	;; now request a display update so that we see the new parameter on screen
	bsf	CS_STAT, CS_STAT_DISPLAY_UPDATE_REQ
	;; clear counter so that cs_menu_timer.inc counts from zero and the menu item is marked for a short time
	clrf	CS_CURSOR_CTR
	;; clear "CS_STAT_CURSOR_FLASH" bit (see cs_menu.inc for the handling)
	bcf	CS_STAT, CS_STAT_CURSOR_FLASH
	;; thats all
	return

    I did have limited success by changing the number "3F" to values like "3E", "3D" etc. but then the binary counting the encoder works with (does it?) got messed up, meaning the page scrolled by x times 1 parameter, buy only on every x-th turn of the encoder.

    I also was able to indeed make the page scroll in full lines by adding values with ADDLW instead of doing the ANDLW but then obviously scrolling back didn't work.

     

    Has anyone been working on something similar and could point me in the right direction?

  16. MBFM Wavetable Issues

    in MIDIbox FM

    Posted

    I'm using setup_pic18f4685_mbfm_v1.asm with settings adjusted to my hardware.

     

     

    I left all 4685-ish settings standard, which means WAVETABLES_IN_RAM is on, and also USE_SHADOW_BUFFERS and DISPLAY_CC_ASSIGNMENT_NAMES.... I'll try it with some of these settings off. Good idea!

     

     

     

    Interesting. When I set WAVETABLES_IN_RAM to 0, I get the following error during the build:

     

    ./src\mbfm_rnd.inc:410:Error [179] Unknown opcode "MBFM_RND_GenerateWTE_Loop"
./src\macros.h:15:Error [113] Symbol not previously defined (MBFM_RND_GenerateWT
E_Loop).
./src\macros.h:15:Error [126] Argument out of range (-16377 not between -1024 an
d 1023)

make: *** [setup_pic18f4685_mbfm_v1.hex] Error 1

     

    Does that mean the random generator needs WAVETABLES_IN_RAM to be on?

  17. MBFM Wavetable Issues

    in MIDIbox FM

    Posted · Edited by Akcija

    Hey, I recently upgraded to v1.4e from v1.1. I used a PIC18F4620 I had lying around instead of the recommended PIC18F4685, and so far everything works just as well.

     

    Only the Wavetable sequencer seems to be broken. I can access and edit it in the menu, but it doesn't seem to have any effect. Could it be because I am using a PIC18F4620?

     

     

    Is anybody else using a an 18F4620? Any ideas?

  19. Native Instruments Maschine MK2 mod with 8 gates and 2 CV out

    in MIDIbox HUIs

    Posted

    Didn't know where MIDIBOX CV related stuff belongs so I post it here...

     

     

     

     

     

    Totally voided my warranty for my Maschine MK2 and installed a small CV interface.

    Why? - I wanted to integrate Maschine with my analog stuff without having to run Maschine's MIDI through an external MIDI-CV converter first. The gates and CVs now feel like a direct extension of Maschine's possibilities. Also, I had a Core8 lying around that I wanted to put to use.

    - 8 gate outputs (5V)
    - 2 CV outputs (NOT 1V/oct but 0-5V)

    So how does this work together with Maschine hard/software?

    SIMPLE:

    - I assign a MIDI out module to a sound (channel 1)

    - I go to keyboard mode on that sound and play pads 1-8. The gates correspond to those 8 pads. Done. Velocity CVs are available for pads 1 and 2.


    DETAILS:

    - The interface is a Midibox CV with one AOUT_LC module. I was surprised how much space there is available under the Maschine PCB. I could fit some other toys there, and I think the next step will be an additional 1V/oct CV interface from midimplant.com.

    - I've assigned the gates to MIDI notes C3, C#3,...G3 and the CVs to velocity of the first two gates. I am using gates and not triggers because you can do some great on/off sequencing stuff with them, e.g. opening/closing a filter etc.

    - If I want to use the CV outputs for smooth progressions, I record the respective pad with note repeat active (the highest note repeat resolution is 1/64th which works quite well for the CVs since the interface itself has a built-in slew rate that I set to 8 ms).

    - Technically, the CV outputs run at about 0.48 V/octave if you will, and they have a precision of 8 bit. They are meant for percussive sequencing and not playing melodies, so I'm good! The background is that the interface runs solely from Maschine's USB power (5V) anyway and I omitted the AOUT_LCs op-amp scaling and offset circuit.

    By the way, I forgot to mention I wouldn't mind if the PIC in question had a Core8 attached to it. I would take the Core, too.

    i just burned bootloaders on some 18F4685 a few days ago, ready to go!

    Do you have a spare one you'd be willing to sell me then?

  24. MBFMControl VST

    in MIDIbox FM

    Posted · Edited by Akcija

    Sorry to resurrect this thread, and/or if I missed another thread. I recently found this VSTi on an old hard disk of mine, and I thought I attach it here since the original link above seems to be outdated!

    (Is this the correct VSTi for this post after all? I have another one here which is called mb_fm_vsti)
