Awesome! Was it pure imagination, or did I hear some unobtrusive stereo effects? Best Regards, Thorsten.

Since we don't hear filter sounds, it's probably a project which plays .sid tunes on an emulated SID. Nils, now it's your turn to demo your emulation which is running on the STM32 :) Best Regards, Thorsten.

In MIOS Studio hex file upload window, set the device ID to 70 (because thats the current one). Get the change_id application, and upload the device_id_00.hex file with this device ID. Thereafter you are able to upload with device ID 00 Best Regards, Thorsten.

Yes! Best Regards, Thorsten.

Btw.: with the setup_sammich_sid.hex file of the latest RC34 release, the LEDs should start to flicker ca. 2 seconds after startup for ca. 3 seconds Best Regards, Thorsten.

Hi, It seems to be a different problem. No, a gray icon indicates a successfully enumerated physical MIDI device. Cannot be excluded yet Cannot be excluded yet Yes, this is a sign of life. Looks nice, no? :) First we should exclude that this isn't a configuration problem with MIOS Studio. Click on "Options->Restore Default Internal Routing" to restore internal connections for the case that you unintentionally removed them. Thereafter ensure, that MIOS Studio In/Out ports are connected to the MIOS32 ports as shown in the newbie guide: http://www.ucapps.de/mios32_bootstrap_newbies.html If this still doesn't help, you could also try to contact the core with the SysEx tool of MIDI-Ox. Send: F0 00 00 7E 32 00 00 01 F7 The core should reply with: F0 00 00 7E 32 00 0F 4D 49 4F 53 33 32 F7 Does this help? Best Regards, Thorsten.

Unfortunately the new Apple extension doesn't support SysEx (yet). It also freezes Java when the device is closed. Meanwhile mmj is only running under MacOS 10.4 and 10.5 if Java 32bit enabled (64bit variant has to be explicitely disabled in Java preferences). Under MacOS 10.6, only the Mandolane driver is working correctly. Best Regards, Thorsten.

You are probably using an unregulated PSU - the voltage will be lower once the PSU is under higher load. Check the voltages again once the ICs are put into the sockets, and the LCD is connected. It could be, that thereafter the 7809 won't output 9V anymore. Best Regards, Thorsten.

No, it works like expected. :) I haven't mentioned the Pull-Up resistor R9 of the core module, which will pull the input voltage to 5V if the pin is not connected to ground. Accordingly, connecting the input pin to 5V doesn't make a difference anymore. So, your core and the MIDIO128 application is working correctly. But: Do you really mean a MBHP_AINX4, or MBHP_DINX4 module? An AIN module (Analog Input) would be the wrong one. Are the MIDI events still retriggered if QH is permanently connected to ground? If not: do you still notice the same issue as you described before with the new DINX4 module? Best Regards, Thorsten.

Great work and funny video presentation! I blogged this, and I'm patiently waiting for the second part :) Best Regards, Thorsten.

Upload the setup_sammich_sid.hex file again, this time with Smart mode and bidirectional MIDI IN/OUT connection. The other .hex files won't work correctly with the hardware, as LEDs/Buttons are assigned differently. Best Regards, Thorsten.

I've compiled the application again with the "base SDK" in the hope that this helps. Please try http://www.ucapps.de/tmp/SIDPLAY_with_ASID.app.zip This version also supports the "Pause" button. Best Regards, Thorsten.

Shipped today: dnode suchoj Best Regards, Thorsten.

Great build and nice video! :) *blogged* Best Regards, Thorsten.

Just answered to the same issue in the german section: I installed MacOS 10.6 meanwhile, therefore I'm not able to check this (mmj doesn't work under Snow Leopard anymore). Either it's sufficient to activate the 32bit version of Java with the Programs->Utilities->Java Preferences app, or you have to install Mandolane (unfortunately the mmj guys discontinued the development) Best Regards, Thorsten.

Mit einem selbstprogrammierten Meta Event waere das schon ohne grossen Aufwand moeglich, doch es stellt sich die Frage, ob es nicht besser waere, die Motorfader-Positionen (sowie LEDs) aus der Software heraus zu kontrollieren, so dass die Informationen bspw. beim Wechseln eines Songs/der Session nicht durcheinander kommen. Welche Software verwendest Du genau? Gruss, Thorsten.

Ich befuerchte, dass Du mit dem Java Update nun genau das gleiche Problem wie alle MacOS 10.6 User hast. Die Jungs von mmj haben den Support leider aufgegeben, so dass Du nun stattdessen den Mandolane Treiber installieren musst (die Lizenzgebuehr ist akzeptabel) Doch es gibt noch Hoffnung: starte mal Programme->Dienstprogramme->Java Einstellungen, und deaktiviere die 64bit Java Option. Gruss, Thorsten.

It is possible to support 64 additional button/LEDs assigned to static MIDI events by adding some code, but for your usecase the application proposed by Nasrudin is much better - it's small and easier to customize (if really required). Best Regards, Thorsten.

Yes, Wilba works on the PCB. :) I remember that you wrote me a PM concerning these buttons a while ago. However, they are far too expensive for such a project. You are free to use these buttons though, but I'm not sure if it will be possible to support them by a standard PCB, as the additional drill holes would increase the costs for everybody. You would have to layout your own PCB. Nice idea, using SMD wouldn't hurt here (contrariwise, it would be easier to solder them at the top of the PCB). But they would also increase the distance to the knobs, accordingly the view angle gets wider, and this increases the danger that the LED light of a certain knob is visible on other knobs as well. Therefore common 3 or 5 mm LEDs would be better. Thanks for the link! The silicon material which was proposed by Per is *much* better than a latex glove or those balloons. Especially the ones with 2mm thickness. It's for example available here: http://www.modulor.de/shop/oxid.php/sid/x/shp/oxbaseshop/cl/details/cnid/AAT/anid/AATD I purchased the 2,0 x 240 x 500 variant for 9.90 EUR and it will be sufficient for the complete 16x16 BLM + some control buttons/LEDs. Of course, you have to take care that the buttons are not too close together - it worked at my side with the distance you can see on the pictures above. Best Regards, Thorsten.

Konfortabler geht es unter Windows mit MIDItrix: http://www.hermannseib.com/miditrix.htm Gruss, Thorsten.

Hallo, einem Freund ist neulich etwas aehnliches passiert... Ist der mittlere Pin des kombinierten MIDI Steckers mit Masse verbunden? Dann waere dies ein Designfehler im Gitarrenverstaerker, und es ist nicht auszuschliessen, dass durch eine Masseschleife zwischen dem MB64 Netzteil->Core MIDI Out->Verstaerker->Steckdose->MB64 Netzteil und der daraus resultierenden Ueberspannung (mindestens) der PIC geschrottet wurde. :-/ Um dem in Zukunft vorzubeugen, hilft nur ein spezielles (selbstgemachtes) MIDI Kabel, bei dem die Masse auf einer Seite *nicht* angeschlossen ist. Gruss, Thorsten.

RC34 has been released - ChangeLog: o fixed race condition in SusKey portamento function o Note Off keys which are not in the note stack are ignored now o implemented CC#123 (All Notes Off) Complies to MIDI spec. Means: only CC#123=0 will unplay all notes, all other values (1..127) are silently ignored o new wavetable control function "Key" allows to select a wavetable step with the currently played note inside the given Begin/End range. E.g., with Begin=0x00, End=0x7f, KEY=on, Par=200 you are able to define different ENV1 Decay parameters for each note. There are much more usecases of course (e.g. different LFO values, different waveforms, Sync/Ring enable/disable in certain keyranges) - be creative :) o Arpeggiator "Easy Chord" function now active in default Lead/Bassline/Multi patch o sammichSID: F2 button now jumps to Knob page by default (especially nice for bassline patches, for other engines the knob assignments are mostly not preconfigured) o Multi Engine: Knob parameter #6 and #7 now allow to control CutOff frequency of left/right channel SID separately. Note that this isn't consistent to Lead/Bassline assignments, but unfortunately there is no other possible solution. o filter page now allows direct L/R channel selection o the full control surface now handles the first press of Osc Select, Env Select, LFO Select and Filter Mode/Channel Select as a "jump to page" function if that page was not displayed, and thereafter, function as a "change selection" function. Thus if you are not on the LFO page, pressing LFO Select jumps to LFO page, and then pressing it again will change the selected LFO. o this is the christmas edition, therefore the Matrix LEDs are flickering during startup ;-) [/xml] Best Regards, Thorsten.

There are several ways to do that. All are using a CC track and modulate the length in Layer C. Start with track length of 4 steps You could gate the sound with the CC#7 (Volume) controller. Advantage: will work on any synth, disadvantage: current volume setting will be overwritten. Therefore I usually prefer to sequence CC#11 (Expression) instead, which should have the same effect. Advantage: it doesn't touch the general volume setting, disadvantage: not supported by all synths, especially not by VST/virtual synths Another good method is to gate the filter cutoff. The CC number depends on your synth. Best Regards, Thorsten.
