It also had bass and treble controls that provided an EQ for the effect. You could also take inputs from multiple sources (mic, instrument) and a mixer, all easily accessible from the front panel. Roland had the foresight to design something that was meant to be played and interacted with. They didn’t just see this as a tape delay with a wet/dry knob, they saw the potential this had to help creative people articulate the music they heard in their head.
You may not like this one (I’m not a huge fan of running either) but it is free, it is exercise, the endorphins will feel great, and it’s a great way to explore a city! Go for runs through the town or Google good running paths in local parks. It’s really easy to get stuck in a van or get used to sitting on the computer or your phone, which definitely leads to back and neck issues, depression and a general shit mood.
