Hi, James You need to read some more info for answers in the MIDIbox HUIs section at first, I think. Regards, Janis

I use a crystal oscilator. The specification for the some 74 series logic ICs : 74HC and 74HCT family characteristics: 74HC Supply: 2 to 6V, small fluctuations are tolerated.74HCT Supply: 5V ±0.5V, a regulated supply is best.Inputs have very high impedance (resistance), this is good because it means they will not affect the part of the circuit where they are connected. However, it also means that unconnected inputs can easily pick up electrical noise and rapidly change between high and low states in an unpredictable way. This is likely to make the IC behave erratically and it will significantly increase the supply current. To prevent problems all unused inputs MUST be connected to the supply (either +Vs or 0V), this applies even if that part of the IC is not being used in the circuit! Note that 74HC inputs cannot be reliably driven by 74LS outputs because the voltage ranges used for logic 0 are not quite compatible. For reliability use 74HCT if the system includes some 74LS ICs.Outputs can sink and source about 4mA if you wish to maintain the correct output voltage to drive logic inputs, but if there is no need to drive any inputs the maximum current is about 20mA. To switch larger currents you can connect a transistor.Fan-out: one output can drive many inputs (50+), except 74LS inputs because these require a higher current and only 10 can be driven.Gate propagation time: about 10ns for a signal to travel through a gate.Frequency: up to 25MHz.Power consumption (of the IC itself) is very low, a few µW. It is much greater at high frequencies, a few mW at 1MHz for example.74LS family TTL characteristics: Supply: 5V ±0.25V, it must be very smooth, a regulated supply is best. In addition to the normal supply smoothing, a 0.1µF capacitor should be connected across the supply near the IC to remove the 'spikes' generated as it switches state, one capacitor is needed for every 4 ICs.Inputs 'float' high to logic 1 if unconnected, but do not rely on this in a permanent (soldered) circuit because the inputs may pick up electrical noise. 1mA must be drawn out to hold inputs at logic 0. In a permanent circuit it is wise to connect any unused inputs to +Vs to ensure good immunity to noise.Outputs can <A href="http://www.kpsec.freeuk.com/components/ic.htm#sinksource">sink up to 16mA (enough to light an LED), but they can source only about 2mA. To switch larger currents you can connect a transistor.Fan-out: one output can drive up to 10 74LS inputs, but many more 74HCT inputs.Gate propagation time: about 10ns for a signal to travel through a gate.Frequency: up to about 35MHz (under the right conditions).Power consumption (of the IC itself) is a few mW.Regards, Janis

Are the 4k7 resistors R7 and R8 both connected ?Are they conected to the +5 volts rail ( or to the another voltage rail) or not ? Any way you can measure the nearest area elements.

May be i am wrong. From the first and the second pictures. The data lines are connected to the left and to the center pin of the encoder, but the right pin is the common pin is grounded. Are your replacement encoder have the same pinout ? http://www.midibox.org/dokuwiki/doku.php?id=encoders Regards, Janis

...Alternatively you can plug the PIC18F4685s which should work as slave temporary into the master socket and upload (and especially test!) the applications from there...

Как Ñ Ð¿Ñ€ÐµÐ´ÑтавлÑÑŽ, речь идёт об Ñтих режимах кнопок ( MB64 , MB 64e ) : A special feature is implemented for the buttons: the behaviour of every button can be specified with the Snapshot Button before a event will be assigned to it: Send learned value when button pressed, send zero when button released. Send learned value only when button pressed, don't send a zero value when button released. Send learned value with the first keypress, send zero value with the second keypress.

Hi, The useful headers are J1_SIDx,J2_SIDx 3pin x 8 pieces I am planning to use a self-build power supply for the MB6582 , too. I will use a transformer ( I have it ) with the 3 separate windings and 3 separate rectifiers , stabilisiers for generating +5,+9 and +12 volts DC supplies. Regards, Janis

Hi, The MB6582 Sids OUT schematic part is as for the SID Module : http://www.ucapps.de/mbhp/mbhp_sid_v3.pdf The some components have the same numbers, too. May be this helps ?. Regards, Janis

ОÑновное внимание в английÑком форуме уделено ÑамоÑтоÑтельному программированию на базе MB64e. Ртакже Ñовет почитать больше о проекте Protodeck. http://www.midibox.org/dokuwiki/doku.php?do=search&id=Protodeck+

Что отноÑитÑÑ Ðº DOUT=128 Ñ Ð½Ðµ уверен, но Ñо входами вÑÑ‘ должно получитÑÑ. Привожу цитату из опиÑÐ°Ð½Ð¸Ñ Ðº MB64e : In priniciple 128 digital inputs are available, every button allocates one input, every rotary encoder allocates 2 inputs. The rotary encoder(s) control 128 virtual pots of a bank, regardless how many physical encoders are connected. The application is very flexible, a lot of different configurations are supported, so don't hesitate to take a look into the main.asm file in order to get an impression about the possibilities.

Hi kris, Are you swaped first and second DINX4 module too? Regards, Janis

Hi, Have you a multimeter ? The Fuse (-es ) are OK ? Is your transformer absolutely dead ? Can you measure the windings ( the primary, the secondaries ) resistances without adding supply voltage? The secondary DC voltage part, can partly tell to you more about voltages: what kind of the voltage stabilisers are used, working voltages on the electrolitic capacitors , etc. Regards, Janis

Datasheets for the relais : http://se.mouser.com/catalog/642/1753.pdf I think, you can connect additional resistor ( 240 - 270 ) ohm in series with the your relay coil and diode's cathode to the +12 volt rail. Rated coil current are two times higher then with the12VDC coil. Regards, Janis

Hi, jaans There are Wilbas schematic diagrams ( with the some minor mistakes , I found it when comparing diagrams with the setup_mb6582. asm file) for the CS pcboard wiring: http://www.midibox.o..._din_wiring.pdf http://www.midibox.o...dout_wiring.pdf Thorsten, Thank You for your advice ! Regards, Janis

There are some default filter calibration value differences : in the setup_6582.asm file : ; Individual Setup File for MB-6582 ;; select default filter calibration value ;; expecting 12bit values (0..4095) ;; will be overwritten by ensemble setting - this is only used as default value for BankStick initialisation! #define DEFAULT_FILTER_CALI_MIN 0 #define DEFAULT_FILTER_CALI_MAX 1536 and in the setup_6581.asm file : ; Prepared Setup File for 6581 SID ;; select default filter calibration value ;; expecting 12bit values (0..4095) ;; will be overwritten by ensemble setting - this is only used as default value for BankStick initialisation! #define DEFAULT_FILTER_CALI_MIN 0 #define DEFAULT_FILTER_CALI_MAX 4095 I am not 100% sure about this.My MB 6582 project is far from this step yet. I have different Sid pairs ,too. Regards, Janis

Может поможет поиÑк, например : "optical encoder " в Ñтраницах форума или WIKI http://picasaweb.google.com/rasteri/Scratchtroller#

http://www.midibox.o...p?id=sammichSID The sammichSID project is a 2 channel variant of the MIDIbox SID V2. Regards, Janis

Hi, Anybody have a spare MB-6582 Baseboard pcb - 1 piece left? I hope to find it somewhere in Europe ! Thanks ! Janis

In the setup*. asm file you can see: BankStick Mode & Allocation Map ; Each BankStick (CS0..CS7) has an own entry ; Set the value to: ; 0: ignore BankStick which could be (or is) connected to the CS address ; 1: if a 32k BankStick (24LC256) is connected and should be used as Pattern Storage (64 patterns) ; 2: if a 64k BankStick (24LC512) is connected and should be used as Pattern Storage (128 patterns) ; 3: if a 32k BankStick is connected and should be used as Song Storage ; 4: if a 64k BankStick is connected and should be used as Song Storage ; NOTE: only one BankStick can be used as Song Storage, only one for Mixer Maps ; If no entry with "mode 3" or "mode 4" is defined, Song mode will be disabled. ; If a BankStick is not connected to the MBSEQ, the appr. entry will have no effect ; If a "MBSEQ Mixer BankStick" is connected, it will be automatically ignored (and not re-formatted) #define DEFAULT_BANKSTICK_MODE_CS0 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS1 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS2 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS3 4 ; Song mode (using CS3 to ensure compatibility with Atmel EEPROMs which only provide 4 CS addresses) #define DEFAULT_BANKSTICK_MODE_CS4 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS5 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS6 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS7 2 ; 64k Are your memory chips are right defined ? Regards, Janis

I remember another older topic with the Led is lit without +5V connected to the OPL3 board. starting from the topic #14,+++ may be it somehow helps. Regards, Janis

"All the voltages read correctly. +/-12V on Pins 4 and 8 of the 74s." you meant : +/-12V on Pins 4 and 11 of the 74s ? The wiring look ok. The better is to connect the audio outputs gnd pin right to your power supply gnd .I think +/-12V common point. If all the chips, a oscillator, electrolytic capacitors are the right placed, may be some soldering problems. Regards, Janis

1. You need 3 supply voltages for the OPL3 module; +5Vdc and a bipolar voltage source ; "Note that the OP amps are powered from a balanced voltage source (+/- 12V). I specified this large voltage range since it allows to take the same PSU like for the MBHP_AOUT module. The TL074s can be alternatively powered from +/-5V to +/-18V. " Do you have stable supply voltages with connected the core and the OPL3 modules ? 2. The MBFM have the four audio outputs you can test it with the mbfm_testtone_v1c.zip application 3. may be you have wrong output settings . sorry, my crystal ball is not so clear tonight. regards, Janis

http://www.avishowte...m/mbhp/buy.html ID 70 MB-6582 Baseboard Parts Kit you can see Parts List with the all included components for this kit, midi din connectors, too. May be I am wrong. : If MB-6582 CS PCB is not as a part of the kit , you need to buy leds and the other stuff separately. Any way you need read much more ... Regards, Janis
