Thank You for nice compliments. This with drums. I think You have probably right, It could be more power. I have good Linn samples. I must to experiment with various compressor settings and reverbs. For Example snare in original Souvenir in China sounds genial and powerfull but I am not sure why (early reflection? reverb-small room? something in the stereo pan?) I must study this...
I make my Simmons on 3 synths pro one Simmons module and can edit it like real SDSV. They are no better samples
Errata corrige about my previous post. I had listened to Youtube with the crappy soundcard of my Laptop and with an even worse pair of headphones...
I have just checked it better now and I think the drums are really good too!
Listening to your version of Arpeggiator and of Souvenir of China I feel the Kick and Snare sound more similar to a Roland TR-707 than to a Linn, they lack "that" punch.
Your Simmons emulation is very good too, a bit more like later Simmons stuff to me.
Anyway these are just small details and Youtube does heavy data compression; the overal sound is really close and all just using Reason. As I said before, very very well done!
