Stretch a hardware with Usine

thomaschamotte · Unread post by **thomaschamotte** » 20 Jul 2017, 19:12

Hi Everyone,

In the configuration of my workspace i'm using a JamMan Digitech Stereo with usine.
Manuel : ftp://ftp.digitech.com/pub/PDFs/Manuals ... 0707-B.pdf

Unfortunately the Jamman can't be clocked with Usine because the jamman doesn't have Midi.

But with the Footswitch FS3X ( who is a propriety of Digitech) i can stretch the Jamman in a realtime.

So my solution is to creat the same signal as the Footswitch with Usine.
In the back of the Footswitch we can read : "this device complies with EN55013 and meets the rquirements of CISPR22 as prescribed by ICES 003". I don't know what does it mean and if it's important.

This is the schematic of the footswitch.

The Output i need is the "UP" output 3 as it's explain in the Manual of the Jamman

For know when i just send a metronom signal in the Jamman it doesn't work.

Do you know if i have to create the same electric wiring in a patch ?? And if i have, could you help me to made it ?

Thank you for reading.

Hi Thomas,

D1 and D2 are here to have tip and ring drove to the ground when using the "loopUp" switch whithout activating REC and Ring.

you'll need to know the voltage of tip and ring, something between 5 and 9 Volts probably

then you'll have to build something to interface Usine with the JamMan :

use the same schematic as above but replace the mechanical switches by optocouplers

http://www.ebay.com/itm/30-50-100-500-8 ... 3016513203

then you need to communicate from Usine to the JamMan : that can be done with a microcontroller, say we use the Teensy that is easy :

it will receive midi from Usine via USB and open and close the optocouplers to give orders to the JamMan.

Cheers

Olivar

Hi Olivar,

Thank you for your answer, it's amazing... I didn't expect this way of reflexion.

Can you tell me if my schematic is correct ?

few errors :

pin numbers for the teensy : :use the digital pins as outputs for example 0,1 & 2

https://www.pjrc.com/teensy/teensyduino.html

use resistor to protect the LED inside the optocouplers : R = 180 Ohms

current in the transistor of the optocoupler should go from 4 to 3 pin

Ho,

Thank you so much...

I just have to go to a micro electronic shop and do it ...

I keep you in text and send you some pictures.

I'm Looking about the price of this adventure.
My built is 55-65$...

Do you think it's a good choice ?
Or do you know some hardware solutions who does exist and cost less than my homemade price ?

it is a 8 bit teensy you need : https://www.pjrc.com/store/teensy.html
by directly from PJRC

you need a TRS jack female, not mono

dont forget the 3 180 Ohms resistors
as well as the 2 1N4001 diodes

go to ebay, it is way cheaper

you"ll need solder as well

where abou Canada do you live ? I'm sure you can find a place with geeks with soldering iron !

I'm Looking for something who could be very interesting.

I bought a ActitioN 8 USB Midi/Jack
This is the Pictures of the Footswitch ActitioN8 and the Short Manual:

https://www.actition.co.uk/

It is a multi functional footswitch very powerful.
It is very easy to use it with usine.

Do You think i can Use directly this footswitch with a Usine Patch to Stretch the Jamman Stereo Digitech ?

no !
it is only for communicating from the "action box" towards Usine.
what you need for the jamman is something to communicate from usine towards the jamman.

what you could try is use the grain sampler of Usine instead of the jamman and control it with the action box !

Ok, i got it.

I already buy the Teensy 8Bits to PJRC.

Thank you a lot for your answers and your Time Oli_Lab.

Hi Oli_Lab,

I have almost all the components to build my special switch we talked about it.
I called it TeenyCouplers because i use the Teensy with optocouplers

As you know i'm living in Toronto and here there are any shops who have the optocouplers you advised me.
So on Ebay i bought 10 pieces of "PC817 PC817C EL817 817 Optocoupler SHARP DIP-4" but the delivery is so long 3 or 4 weeks...

So i found this website http://ca.mouser.com/search/refine.aspx?N=11624526 who can send me the optocouplers quickly.

The thing is, there is so many optocouplers i don't know witch one choose.

Can you help me for these last step ?

Thank you for reading.

Hi Oli_Lab,
I have made a new Topic from our conversation to the way to patch the Tennsy in Usine.
New Topic : http://www.sensomusic.org/forums/viewtopic.php?id=5843

In conclusion i will certainly make an article about it.

Peace.
