if anyone wants to disclose... how much can/did you make with a system like this (towards the dawn of the crypto hype, not now)? awesome!

At peak (December 2017 to February 2018), my small python bot was making between 500 to a couple thousands dollars per day. It was even possible to do arbitrage by hand at that time since you sometimes had a 10-20% difference between the markets.

Can confirm. Early January 2018 I made $10k in a week because the BTC/JPY price was 10% higher than the BTC/USD price. It required a partner in Japan and lots of international money remittances though...

How did you handle the delay of moving coins between exchanges?

If you have enough money - you can spread it among various exchanges into pre-defined coins and just rebalancing it along the usual trading.

any good article about coin arbitrage ? right now I'm mostly curious about the operation

Here are some sequencers you could look at (that I've personally owned)

Zaquencer - $200. The most sequencer you can get at that price point. But lots of knob turning, no real displays. Its fun though.

Toraiz Squid - $600. But it has some great features, and its very 'playable'. You can also drag and drop all of your midi from the device into the DAW.

I would suggest starting with purchasing a MIDI interface and a sequencer. Just use them to control software instruments in your DAW.

This is my workflow. Make a bunch of patterns in a sequencer. Record audio or MIDI into the DAW. Arrange the patterns. You get you brainstorming done on the hardware but the editing on the software.

These tools are the industry standard for creating and recording music digitally.

They are suitable for hobbyists to professional level.

I personally am a hobbyist musician and programmer by profession. I'd imagine many others here are like me as well.

I'm an owner of Bitwig and a huge fan; that being said I think it's more fair to say that Bitwig supports Ableton Push with a few asterisks.

It is supported as far as the Bitwig scripting API can support it. The experience is not the same as using Push natively with Ableton.

What are the differences? Does the screen work?

I have a Push 2 with Ableton.

Here are the open issues for the Bitwig Push controller scripts to get a sense of what's not working: https://github.com/git-moss/DrivenByMoss/issues?utf8=%E2%9C%...
