Hi Garfield,
Thanks for taking part to the conversation and your kind words about my badly mixed music :-p
The Waldorf NW-1 looks nice but it's way too wide for my rack. I have decided that if I change the oscillator, I am going to go with Noise Engineering Loquelic Iteritas. Demos sound rad, it's only 10HP with nice modulation options and most importantly, I think it would be the one I'd have the most fun with. Already have a lot of respect for that manufacturer since I love the MD and every minute with the BIA is a real pleasure. Seeing how much distortion I was using when making music on Elektron machines + computer, I think something small and nasty like the Viol Ruina could also be a good thing for my rack too, I did some experimentation with the Overdrive in my Pico DSP but I wish I could turn the drive knob further :)
I'll have a look at Springray II. To be honest, I'd have to try different options with the sound sources within my rack, given that I clearly don't know enough about reverbs to have an opinion. I think that a reverb upgrade would have to wait for a bigger case, which isn't planned for the near future, and for a day when I would have some idea of what I need.
I don't know anything about the Vermona drum machine I'm afraid but I have owned the A4 mark 1 for a few years, it's a very deep synth that rewards dedicated exploration. I have read criticism about it sounding "thin" but in my experience it comes down to user knowledge about its sweet spots and general substractive synths programming. I recommend trying to get drums sounds out of it too, it can be a great drum machine as well, especially using sound locks. I wish you many hours of fun with it !
I'm still happy about the T-sL, definitely. I find its core sound just powerful and beautiful. It's surprisingly deep for only 6hp, its many outputs offer a wide sound palette from mellow to very harsh. The size could be viewed as a downside though, because if you use a lot of outputs and feed its inputs at the same time, the small knobs can be hard to get to with your hands after everything is patched. If you can live with that, it's wonderful IMHO.
On top of my Mac being broken, I had to send back my Intellijel Mixup modules (dead channel 1, already fixed by the awesome Intellijel support and on its way back to me) so I don't even have a complete setup now. Gives me some time to study modules in more isolation I guess. As soon as I'm back on tracks and have recorded something, I'll let you know ;)
Best,
Diego
