guess I'm the only one who's using oldskool Hardware methods.....I use both an Akai MPC4000 and a Roland MV8800
I Use these mainly as I prefer to stick to Hardware sequencers and both the MV/MPC allow me to compose and record in a Very Live way,So I can add a live playing element to the sequencing Both Machines are very easy and quick to use without the need to sit for hours doing tedious fine adjustments to MIDI data,(although i do some of this after)and they allow me to work in a way that I can keep writing/Composing and simply build tracks as I go without interupting the workflow or inspiration,
I've never found a decent software platform that allowed me to work in a quick and intuitive way like this without losing enthusiasm or having issues with timing and syncing running large Midi hardware rigs or spending more time combing the fine details with a mouse,I've used many software sequencers,just was never satisfied with the timing(except the old Atari/Cubase,Roland MV8800 is very much like Cubase/atari style when used with monitor/mouse)
The MPC is the main sequencing source in the studio simply as its the main central Hub to the midi gear because of its midi outputs the MV is a secondary sequencer(because it only has 2 Midi outs and I need 4 For all the Midi gear I have)the MV is used with a Triton synth for composing/getting ideas down as its not in my studio,so I use this to compose on away from the studio
The only software sequencer I use(minimally) and would look to use in the future(To maybe replace the MPC/MV) would be Record/Reason(if they included External Multiple Midi control,although how much I would use it would depend on its Midi timing With a large hardware setup)I do Like the V4 sequencer update,but just prefer to sequence everything from the MPC4K,including Reason used as a sound module rather than its own sequencer simply because I love the MPC workflow and know the sequencer inside out
