Elbrus-2S+ Elbrus-2S+ Elbrus-2S+ () is a multi-core microprocessor based on the Elbrus 2000 architecture developed by Moscow Center of SPARC Technologies (MCST) There are multiple reports regarding the evolution of this technology for the purpose of import substitution in Russia, which was raised by several ministries on July 2014, due to economic sanctions in response to 2014 pro-Russian unrest in Ukraine. In December 2014, it was announced that Mikron start pilot production of a dual-core variant of this microprocessor called Elbrus-2SM () using a 90 nanometer CMOS manufacturing process in Zelenograd, Russia. The Elbrus-4S CPU is reported to have built in
Roland MT-32 respond on input MIDI channels 2~9 and 10 respectively. By consequence, MIDI files using the popular channel 1 or the other channels 11~16 cannot have those parts played on the MT-32. However, the MT-32's melodic parts can be shifted down to respond to channels 1~8 using a button combination or through MIDI "system exclusive" messages, enabling improved compatibility with non-MT-32-specific MIDI sequences. Additionally, in 1993 Roland released the "GM2MT" SysEx pack, which can be used to reprogram the MT-32 and compatibles to match General MIDI specifications as close as possible. 64 of the 128 patches (the limit of possible variations)
