My studio is very small; just 4.2sq.m or 45sq.ft
As the pieces of equipment increase, there needs to be some rearrangement. Therefore, I tried my hand into carpentry and built a couple of desks and a stand. The result is shown in the photo.
I list below the synthesizers that I have and add a short comment for each one:
Yamaha MODX6: my workhorse synth. I use it for everything I make. All music starts from this one. Midi is recorded in it first and then transferred to my Digital Audio Workstation. Any other synth is connected to the MODX and is assigned a track. Practically, I use the other synthesizers only for synthesis and I could do with modules only to save space but having the keys is often convenient. Usually, there are two synths connected to and driven by the MODX, which can also provide a wealth of FX to any sound coming in through A/D.
Korg Wavestate: this is my second most used synth and features in many of my releases. It is extremely convenient that I have both the hardware synth and the plugin (Native) version which allows me to further edit the sound in my DAW. It is the only synthesizer that I feel that its sound would be very hard to approach with my MODX. Feels really unique.
Roland Jupiter Xm: It is a real monster of a virtual analogue synth and further to the models like Jupiter-8, Juno-106, etc., it also has plenty of traditional and novel Roland PCM sounds. However, it hasn't made it into any of my releases yet. For some reason I will always take the midi I have recorded with it and change it to the sound of one of my software plugins. Regardless, I love this and surely, it will feature in my future releases.
Regarding software synths, I always use SurgeXT which is my top choice. I also have U-he Zebra-2 which is a great synth but if I can get the sound that I want with SurgeXT, I know I will get there quicker. Both are amazing.
The computer on the photo is my Thinkpad T14 running Ardour on MX Linux.
