Unfortunately, I do not have enough idea of asm, but I was able to implement at least a CC 120 (for a chosen midi channel), which reloads the same preset, which internally resets the registers. Maybe it is useful for someone to manually delete the hanging tone. At least you have to add following code in these files: sid_midi.inc (insert before CC 123 detection: --> ;; check if All Notes Off (CC#123 == 0)) ;; ####################################################### ;; # CC 120 reload preset ;; ####################################################### ;; check if CC 120 (CC#120) movlw 0x78 cpfseq SID_MIDI_PARAMETER1, BANKED rgoto SID_MIDI_CC_NoInitPreset movf SID_MIDI_PARAMETER2, BANKED bz SID_MIDI_CC_NoInitPreset SID_MIDI_CC_InitPreset goto CS_MENU_MS_NotifyInitPreset SID_MIDI_CC_NoInitPreset ;; ####################################################### ;; # END MODIFICATION ;; ####################################################### cs_menu_ms.inc (insert before program change routine -> ;; This function is called to forward a Program Change event to the control surface) ;; ####################################################### ;; # init/reload preset routine ;; ####################################################### ;; -------------------------------------------------------------------------- ;; This function is called to forward a Init Preset event to the control surface ;; Input: ;; o midi channel in SID_CURRENT_CHANNEL ;; o patch number in SID_MIDI_PARAMETER2 of INDF0 lower value ;; -------------------------------------------------------------------------- CS_MENU_MS_NotifyInitPreset ;; request patch send to SIDs with matching channel number SET_BSR SID_BASE clrf PRODL ; PRODL used as counter CS_MENU_MS_NotifyInitPresetL ;; calc pointer to channel entry lfsr FSR0, CS_MENU_SID_M_CHN movf PRODL, W addwf FSR0L, F ;; check if channel number matches movf INDF0, W xorwf SID_CURRENT_CHANNEL, W, BANKED andlw 0x0f bnz CS_MENU_MS_NotifyInitPresetLN ;; get patch number matches (in this case don't change the patch) movlw (CS_MENU_SID_M_PATCH-CS_MENU_SID_M_CHN) & 0xff addwf FSR0L, F andlw 0x7f ;; copy INDF0 to SID_MIDI_PARAMETER2 and masked 0x7f movf INDF0, W andlw 0x7f movwf SID_MIDI_PARAMETER2 ;; store patch number movff SID_MIDI_PARAMETER2, INDF0 ;; skip if patch change already requested movlw (CS_MENU_TX_M_CTR-CS_MENU_SID_M_PATCH) & 0xff addwf FSR0L, F BRA_IFSET INDF0, 7, ACCESS, CS_MENU_MS_NotifyInitPresetLN ;; request patch change movlw 0x81 movwf INDF0 CS_MENU_MS_NotifyInitPresetLN incf PRODL, F BRA_IFCLR PRODL, 2, ACCESS, CS_MENU_MS_NotifyInitPresetL return ;; ####################################################### ;; # END MODIFICATION ;; ####################################################### I know, it's not the best solution (I miss my assembler depth ... actually I just wanted to refresh the SR ). However, you must be aware that this will cause any changes to the preset to be lost. ..most of the code was taken from the program change routine. This CC is useful for me, after the 6581 was used and the SID is still audible after use. I can then trigger this CC to end the hanging sound. Greetings, rio

yes you are right, I could now break it down on two devices, where it did not work as expected. Thanks for the explanation. Greetings, rio

################################################## # Running status optimisation # Enabled by default, should be disabled if a MIDI # device connected to a MIDI port doesn't fully # comply to the MIDI specification. # Expects two parameters: port number and 0/1 to # disable/enable the optimisation. ################################################## Can someone explain me what the difference is to 'normal' midi out or what exactly does that do? Most of my synths/device don't understand this optimization... Greetings, rio

I would like to take this opportunity to say "thank you" again. After years of working with it, I can still discover new things, implement my ideas and nice that the firmware for the LPC17 was still in place, which I still use. The device is or remains the heart of my synthesizer & it runs stable & fine - I do not know any other hardware that covers the range or is so flexibly applicable. By the way, mentioned that the firmware is also open source. Best regards, rio

Hi, Yesterday I played around with the loopback feature. If I had set a track to bus 1 then I can already see the NRPN LSB descriptions for the CC inside that track - nice, but If i choose another bus (2,3,4) the standard description of the CCs is shown again. Is that intended or a visual bug? best regards, rio

Thank you!

since V4.093: Is it possible to include this representation as an option (e.g. display edit notes transposed: yes/no) in the option page? For me, it's quite difficult to find or remember the original/root notes of the track again when editing live.

Hi, i am from germany and want take the lpc17 Core board (5€) and the full Lpc17 core (25€). Pls PM. greetings, rio

hi, When "Midi Remote Key" is pressed, you can control multiple SEQ functions with different midi notes (which can be triggered by your controller or keyboard): http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fsequencers%2Fmidibox_seq_v4%2Fdoc%2Fmbseqv4_remote_functions.txt&peg=2562 PS: If you have general questions to "how to use the SEQ", then it's best to create an own thread. Greetings, rio

As i remember, C-6 is the default remote key that is configurable to V4.093 in MBSEQ_HW.V4 file: ################################################## # MIDI Remote Keyboard Function ################################################## # The note number which activates the remote function # 96 = C-6 (some MIDI monitors display C-5) # 0 disables the remote keyboard function MIDI_REMOTE_KEY 96 # The CC number which activates the remote function # (e.g. to control it with a footswitch) # Allowed numbers: 1-127 for CC#1..CC#127 # 0 disables the function (default) MIDI_REMOTE_CC 0 ..but since V4.094, it's configurable in Option Page, like TK mentioned here: http://midibox.org/forums/topic/13137-midibox-seq-v4-release-feedback/?page=49#comment-179576 Greetings, rio

Hi, I've been thinking a bit about how to get ride off the SID 6581 'hanging VCA' bug in a different way (except of the use of a noise gate). In most cases, I only want to stop that annoying sound in an easy way at silence - so at the end of a song or a jam. At the moment I just change a preset for SID 6581 core(s) to stop the sound manually. But that is awkward. So my question: Is it possible to trigger the SID_SR_Refresh for predefined SID ID(s) by an special CC or (or thinkable by "Midi Stop")? maybe configured for concerned core IDs in * .asm? Sadly, I just do not have enough knowledge of ASM and the SID engine itself, but I can understand some sources looking over it. E.g. I do not know how to address a SID engine directly for the case of refreshing and if that works as expected. For example, I would like to know how to select the respective SID Core (or how parameters needs to be configured for that use case), which is needed before a SID_SR_Refresh. Pls, could someone possibly point me to the right direction? Greetings, rio

hey, just a few tips from my own experience: Make sure not to touch the pins or to create fast friction there. Ground yourself to earth for a few seconds before removing/inserting the chips (for example, 2-3 seconds touching the heater in the room) or better wearing an ESD protection bracelet while working, which is connected e.g. to the heater. Maybe the chip (or even some parts of it inside) just died of old age or just because of an ESD someday. But you can also check for a cold solder of pins on the board, where by mechanical changes the pins sometimes have contact or not. greetings, rio

Hey, LM387 is expensive ....! And is A1 also a LM387? greetings, rio

hey, What does A1 stand for? greetings, rio what about that:

thx, but therefor I haven't the negative VCC– for TL082 or TL084. I search a solution, where I can reuse the 9V~ or 14Vdc or 5Vdc of C64 optimized PSU schematic. Greetings, EDIT: Could that following circuit (Figure. 3) work too? No additional OPAmp is needed: https://www.edn.com/electronics-blogs/the-practicing-instrumentation-engineer/4422750/Simple-circuits-reduce-regulator-noise-floor rio

Hello, I was looking for a simple stereo solution for a noise gate to reduce noise of a pair of SID 6581. I know, that is a common thread already here: ... but, there are some limitations for me. For example, it is not soooo easy to get all the parts or transistors must matched (!) and so I was more looking for a rather simple smart solution. So I found the following: http://www.electroschematics.com/250/stereo-noise-blanker-suppressor-limiter/ which looks very simple. But the author mentioned: Would that be ok for the SID 6581? Or is there something against the solution or would the output voltage of the SID be too high for that? Greetings, rio

Could be a result of ESD. The chips should be handled with care (e.g. esd protection) greetings

On which PIC type you are trying upload sidv2?

upps.. since my last update (from svn rev.2551 to rev.2561) my SEQ switched (always) after booting to the option 'JAM' instead "T&A" on the following page:

yes, the way is correct: 1. burn bootloader, 2. transfer MIOS via MIDI 3. transfer App via MIDI that PICS are kinda robust!! I don't think they are defected anyhow. but take care about your chip types: http://www.sprut.de/electronic/pic/typenliste_16_bit_kern.txt Name Pins Prog EEPRM TMR Capt PWM UART SSP CAN USB ADC IO- [kB] -ure CMP /SPI I2C Pins 18F4585 40 48 1024 4 2 2 1/1 1/1 1 - 11 36 18F4680 40 64 1024 4 2 2 1/1 1/1 1 - 11 36 18F4685 40 96 1024 4 2 2 1/1 1/1 1 - 11 36 as you can see, your selected types haven't enough prog. RAM for your app (in the case of MBSIDV2). the last number of the PIC18F4685 has a special meaning: 5 - 150% FLASH-Memory and more RAM But any other PIC18F4520 app would fit in that range. You can use that pics for own programming stuff too... ;) If you need help getting SDCC & last Code::Blocks running for that case, do not hesitate to ask me. greetings!
