What do i need to make ES-4 a midi interface?

[TS-12]

after trying numerous usb-midi interfaces, and being disappointed with them. I decided to try ES-4.

I need to sequence about 3 external multi-timbral hardware synths.
but for start at least one ext. hardware synth.

So what do I need to get 16 midi channels out of cubase to korg tr-rack?
i watched the videos but still don't get it, what exactly do i need, that rac for es-4, spdif to midi etc..

You need

- an ES-4 + ES-4 Gate Expander OR ES-3 + ES-5 (ES-3 Expander)

- a case / power supply, if you don't already have a Eurorack modular

- an adaptor e.g. http://www.flickr.com/photos/expertslee ... 7543887181 or make your own minijack-to-DIN cable

- the Silent Way ES-4 Controller plug-in (free)

ok. one more question: is it possible to transmit multiple midi channels thru this set-up?

[os]

Yes, each physical port can transmit 16 channels as normal.

[TS-12]

Yes, each physical port can transmit 16 channels as normal.

ok, so since gate expander has 8 ports, I can use each port to transmit 16 usual midi channels, each of the 8 ports can work as individual midi port simultaneously?

[os]

Yes.

hopefully the last questions about my pre-purchase:

1)Since my RME Babyface soundcard has adat lightpipe i/o.
Can I use ES-3 with expander, instead of es-4 w/expander, for mult-channel-midi output?

2)Will all this work at a 16/44.1k ?

3)Where do i find Eurorack and Powersupply distributor that will ship to U.S.? (don't have any luck finding it)

[os]

1) Yes. You want ES-3 and ES-5.

2) Probably. Very few devices seem not to work at 44.1. So far everything seems to work at 48.

3) There are many places that sell this stuff in the US. E.g.
