USB-powered MIDI keyboard & Analog Four

@tornfrayed Sweatwater told me 3 weeks ago that they should ship to the in 4-6 weeks… Now keep in mind they were supposed to be out a year ago, but the company I believe went through some growing pains and the production company in China screwed them. At least that was the story I got at NAMM this year…

Thanks. I’ve previously owned a machinedrum and mono machine a decade or so ago before giving up music. Then a few years ago I came back completely ITB and am now looking to go hybrid. I really appreciate the quick answer and look forward to getting an A4!

@donato NP. the A4 is awesome to get back into the groove. compared to the MnM and the MD it is simple to wrap your mind’s song around. having all of the elektron devices it was the easiest to grasp. when you have the USB keyboard and the A4, you will need a app which directs the MIDI from the keyboard to the A4. if you are using a computer, is it a Mac or PC?

Just a note here in favour of the iConnectMIDI4…

Received mine 2 days ago from zzsounds (USA) and this is a neat bit of kit.

You need to connect to a computer to program it up, but after that it can work standalone…

it supports:

4 MIDI Din ports
1 USB host port (class compliant midi devices… like keyboard controllers)

In this respect it works as a standalone midi router, with port routing, channel mapping, filtering, and most unusually, controller mapping.

This last bit is great news, you can map at a port output (as data leaves the box), and/or port input (as data enters the box). As a test I have faders off of an mc-808 controlling filters and delay on a Virus and a Nova…which both have different cc maps to the mc-808. By mapping at the synth out/in ports I can also control the Virus now from the Nova… Only 8 maps per port per direction, but enough for the essentials.

As standalone, things get screwy when you connect an iPad, You lose Audio so an ios device should be connected to a midi port, not the usb port.

Ignoring the audio, this is well priced box that works well as a standalone configurable midi router with healthy capabilities… the mapping is the bonus to gear heads.

Does it do MIDI merging as well?

yes, you can confuse yourself no end :slight_smile:

Thanks! Yeah, I’m using Studio One on a Mac.

Does Studio One(the pre sonnos app I believe) have midi control tracks if not you may need a midi bridge.

Hi. I don’t quite understand the question, maybe someone else can answer. Presonus Studio One 2 is a fully-fledged sequencer, similar to things like Logic, Cubase, etc. Maybe someone else can answer?

So then you can do a few things. you can set MIDI for the track to something other then 1, like 4 or 6. but like ten for instance is where most drummachine midi is sent.

then set the track in studio one to control MIDI 4 or 6. this will allow you to have studio one control multiple machines.

Am I answering your question now?

Yes. Thank you.

Also with some set-ups you can split the keyboard. so it plays from higher octave keys one instrument while the lower octave plays another instrument.

MIDI is very flexible but can be confusing and gets confused easily if you add a lot of complex routing. having a MIDI Hub like mentioned before the ICM4+ complexity stays in one place and problems are therefore easier to track down.

Interesting topic!

I wonder if i could connect my Microbrute via USB over my iconnect midi2+ with the A4…would save me one Midi controller keyboard.

EDIT: Damn…the ICM2+, as well as the A4 and Microbrute have only all Standard B USB connector plugs. Where can i find a USB standard B to standard B cable? conrad.de didn´t help me further.

Ok, i just found out that the ICM2+ can´t act as a USB host. I am going to exchange it with the ICM4+. That can have an USB hub attached and then i don´t need any converter cables. A4 can be connected by Midi to the ICM4+, the Microbrute can be connected with a standard USB A to B cable to an USB hub, and the hub get´s connected to the ICM4+.

To the OP - a neat solution for studio use is to just buy a power socket bay that includes USB power. Very common these days and can be had for around 20 bucks.

So you can omit the walwart from the setup by going USB cable from your bay to power USB keyboard, then midi out keyboard to A4 - this works with any keyboard like the KMI’s that do both USB and DIN.

Also I’ll quite often leech power from my laptop via USB even if I’m not using it to control the A4. So I might just be using the laptop as an audio recorder, but I can still hook my Ultranova up using USB for the power and then use it as a MIDI controller (via a MIDI cable) for the A4. Doesn’t cut down on cables, but as mentioned above, it’s one less wall wart and socket space to worry about.

I know it’s pretty old topic but it might help someone later so I am posting my reply…

If your issue is purely related to powering the midi device, you might consider creating a USB power injection cable. If you look into the spec of USB socket, you’ll notice only 2 connections are used for data transfer (D+ and D-), then you have another two as VCC (voltage) and GND (ground).

Sometimes you can find such cables online, but it’s very simple to do it at home, if you are not afraid of a bit soldering ; )
