Yes I do remember those patches. And you are correct they definately were on the MT32. I really liked the drum and percussion sounds on it as well. Even though the MT32 was lofi when you look back, it had a great balance and mix when used as a multitimbral sound source. All the sounds sat well together in the mix and nothing ever seemed to overpower other sounds. I remember using other multitimbral units after the MT32 that took a lot more work to get everything to coexist comfortably in the overall mix. Roland really did a great job with the MT32 and I wish I still had it actually.
