Let's start with an instrument like the Malstrom synth module and go through the paces and see what it takes to start your session. As you select the module and drag and drop it into the rack, this begins your track build up of the music you are creating. Reason 8's exponential power lies in the combination of multiple sound modules and how they can be connected through virtual cables of insand outs on the "back side" of all the virtual units. Even though physically connecting these virtual cables is not necessary as the software will automatically combine units together, having the ability to link in any series or configuration you would like gives you the opportunity to create unique sound combinations through interconnections of these modules, processors, and editing devices. Another way to create the sound module in the rack is to just grab the patch first and drag it into the rack. The sound module unit is created as soon as you drop the patch into the rack. This also holds true if you just drag it onto the sequencer window and track. So we can create a unique rack of sounds and samples that will be utilized for sequencing. We can go beyond this, with the inclusion of external hardware sound modules, keyboards, or drum machines being connected and tracked via the MIDI sequencer and synced either for MIDI recording and/or live recordable external sounds and editing. And with the new Softube amps specifically for the guitar/bass patches (which sound great), the processing unit can also be used for virtual instruments and/or external hardware modules or keyboards.
