I still have my favorite and best analog synths,,, EMS Synthi-A, Arp 2600, Arp Odyssey, String Ensemble, Mini Moog and some others. These analog synths definitely sound and act differently than their plug-in counterparts,, and in many case I prefer the real/ old ones. The tones generally are wider, more vibrant, less sterile/clean more alive and claim more musical space. However, I find plenty of uses for plug in instruments, and I have been analog/digital hybrid-ing since 1995 when I bought my first Ensoniq ASR-10 Sampling Keyboard. Here's how and why:
Already by 1995 I wanted a way of creating 50 complex analog synth patches and using them on tour across USA without having to bring six synths and program them live onstage. I already was using ASR-10, Ensoniq Mirage, Roland JD990 and Arp Odyssey live, and playing a guitar and a bass as well! By making multiple keyboard maps and sampling odd sounds into the ASR-10, I could do it all, and have my best sounds and play live with no hiccups or hassles!
Fast forward to 2018, and I used a combination of Arturia Mini Moog, G-force Oddity and my own synth samples in EXS-24 sampler inside of Mainstage, all triggered by a 4 octave and 2 octave midi controller. We were touring South America, and it was a great solution for taking trains, busses, taxis and planes and not too much extra weight/luggage.
I currently use soft-synths and drum machines for these reasons:
1. Im producing a band (overseas) and want to record ambient synth sounds or a keyboard solo, and there are no cool keyboards at the studio.
2. I dont on a Mellotron, but want to have a Mellotron choir or flute part in my song
3. I want to make deeply layered sequences, and none of my analog synths have midi, nor inbuilt sequencers!
what about that?-- cheeers!
