I think the RX5 is an awesome drum machine. Made me see the value in old flagship instruments. The design logic is robust and nothing in the workflow lags.

I have a Pharmasonic ROM cartridge for mine.

I also had a Roland boutique d-50 clone which was awesome, but I sold it which i regret.

Some things I buy more than once. I buy it. Don’t use it. Sell it.

Then find myself with the same problem and go through the same research and come to the same conclusion.

The net costs are just rent in my mind. Or the difference between getting a great deal and paying more than I might have. Or just money I spent on my hobby.
