mmm.. No error. VAT in Italy is 26%

I'd like to use the 8 adat optical channels in my motu traveler in order to use 4 additional stereo analog ins. I don't want to buy an alesis AI3 for this purpose (very expensive in my opinion), so after reading some discussions about using the AK's and CS I asked myself if you guys have made something similar. I was considering using the al1401. Is it possible to adapt it to the ADC/preamp Pilo designed (he published it in the portal sideproject forum)? Using 4 al1101 (so 4 ADC circuit based on pilo schematics to have preamps too) I could have 4 stereo channel digital stream which can be routed to a single AL1401 for ADAT conversion. Please correct me if I'm wrong. I would like to convert S/PDIF and AES EBU too for 2 additional analog stereo ins, maybe using after the above mentioned Pilo's preamp a CS8402A encoder. Please help me :D

on ALBS.de, their proforma invoice charges me 26%. That was what Schmidt told me ???

Well I need the motorfaders as soon as possible, I'll order them from albs by myself (very expensive because of german taxes) . That was a bad hit, I could save a lot, but that's life. Thanks anyway

Hi screaming rabbit. What's the status of the motorfaders? New from the bulkorder in the bag?

Sure, I'm from Italy, Rome.

Very interesting :D could you give me schematics and tell me the approximate price for each analog to adat converter (I'm thinking of using the 8 adat mono channels provided in the motu 828MKII as 4 stereo additional analog ins)? Thank you very much

Does anyone know about schematic for an ADC converter to use analog balanced inputs and digitize them to send in S/PDIF input? Thanks in advance

Hi! Where are you from? I'm a potential buyer, but I need to know from where you would send the goods

After reading the discussion about XY touchpad by spectrasymbol, I ordered form them flex sensors samples. They work for MB64, but maybe some software change is required: They act as potential dividers, a resistive carbon strip gives resistances from 80Kohm to 160Kohm. Vin-----------VR1----------Vout | | R2 (not variable) Vout=5*(R2/VR1+R2) | | Ground Sorry for the poor schematics, but I managed to let a flex sensor work with R2=80Kohm on MB64, but since the output voltage goes from 1,6V to 2,5V I have limited action so only variations from 64 to 30. Is it possible to change this (to let one flex sensor go from 64 to 0 and another from 64 to 127 to use them as pitch bend) via software or hardware?

I forgot: the best deal would be to use one vfd 2x16 to monitor a stereo signal

Thanks raphael, the question is: the datasheet shows how to interface the lm3915 to VFD bargraph. normal VFD's (I'm used only to noritake U-series so same interface as HD44780) offer same pinning of standard hd44780 lcd's. there are not as many pin as character number on display, that's because I don't know how to interface the LM3915 to a VFD

Hi, I thought about it, but since I designed the circuit with an LM3915 to monitor on logarithmic scale audio signals amplitude, I don't know how to implement it to a normal VFD. Have you got some clues on how to do it (LM3915 can drive up to 10 leds, more than 10 would be really appreciated ;) Maybe using another IC?

Hello, does anyone know where to find a 2x10 vfd bargraph (1x10 ok too)? Thanks in advance

who's the sick who enslaved a doll to this?! :D

Hey Smash teach me those tricks and let's go for a tour around the world! I order 100000000000000 leds (don't take me seriously :D)

Well, Leds cannot be supplied with direct voltages, you need to limit currents with resistors (Dout provide 220Ohm resistors for each line). My leds work ok and I bought them from Smash

Thank you very much ;)

Hello, Here's a powering issue. I need to power on a Midibox SID with 2 8580, but I don't like the PSU arrangement. I have a power supply which delivers 12V and 6.3A. The current is very high, and my MBsid has a power consumption of approximately 800mA. Maybe some fuse protection? Thanks in advance

With the latest MB64E app it is possible to use pots/faders. Good luck

I was quicker than expected ;) Unfortunately I told you bad, I received some encoders by Smash and they're not just 2 buttons (sorry Iìve never dealt with them outside the connections suggested by MB community and in addiction some encoders work differently from others), so my solution is not possible without changing the code. If you want pots with snap mode you need to build MB64+MB64E, otherwise with a single MB64E you'll have encoders and pots without snap mode. Bye

Thanks Rambinator, I have no problem using 2 ports as Iìve got a midex 8 so plenty of ports! :D thanks for the advice ;) Lide: As soon as I can I'll try it on my MB64 (I need to open the chassis to try it) gimme a week ;)

Hi rambinator, isn't it possible to midichain MBLC to MB64E? Midibox link protocol under ucapps should state this possibility (I didn't this so far, but I will), MB64E with midi merging on

if this are the minimum requirements here's what you can do with MB64 MB64: you can have up to 64 pots, so 11 faders+ 2x11 pots (2 in each track)+1 fader for crossfade (I think using a motorfader for this function would be a waste) = 34 pots used and 30 free; you can have up to 64 led and 64 buttons, so 8 buttons/led+ 3x11 buttons/leds for tracks = 41 buttons/leds used and 23 buttons/leds free; for the endless knob you should try this (I have not tried it so i'm not sure it will work): if you connect an encoder to the din module you use for the buttons, you use 2 digital ins: the encoder should work as 2 buttons, so when you move it counterclockwise it's like you press scroll down and when you turn it clockwise it's like you press scroll up. you assign one to scroll down highlighted scene and the other to scroll up highlighted scene via live and voila. This way you can add 30 pots to the quoted configuration and 21 buttons :D and you have snap/relative/parallax

In MBLC you can use only 8 motorfaders (I'm not very sure if the MBLC application supports more than 8 analog inputs). If you want to use more encoders you must eliminate some of the buttons and change the DIN assignments Well I suggest to build a MBLC+MB64E, this way you'll need 2 cores and you'll have to link them to one midi out or an RS232 port. This way, you'll have enough encoders and faders/pots+the advantages of motorfaders and mackie control protocol+ less coding issues :D a lot depends by your budget, one additional core is not expensive, the true problem is represented by the motorfaders and the pots/faders.
