First look: had a go with the ensemble instrument first, which is all one-shots. It's logically laid out with pictures to show which instruments are being activated and color-coded keys, one key for each instrument and articulation. If this is how you normally use percussion libraries (like I do) you'll be up and running in 30 seconds. Djembe, bongos, congas and timbales are tunable.
Next I pulled up the sequencer. The array of blue lights that dominate the display might seem daunting at first glance, but then you'll realize it's just a step sequencer. If you've used any step sequencer, including SONAR's, you'll have no problem. Click a blue light to turn an instrument on, click it again to turn it off. Like SONAR's step sequencer you can program in real time or step-record, can choose sequence lengths of between 1 and 32 steps, and specify swing. The sliders along the bottom are volume controls.
You also get a proper mixer view, where you can pan each instrument, select the microphone, and apply delay and/or reverb to each instrument independently. There is also a compressor, but it doesn't appear to have any controls and applies to the full mix. The green lights at top are microphone enable buttons.
There are 24 sequences already programmed in, so you can have some fun with it straight out of the box. There's a well-written user guide, but you won't need it right away. Although I did learn from reading what "FL" stands for (flam). Probably would have figured that one out eventually.
Strange thing...in two of the low conga samples you can hear a voice. Because of the round-robins you'll need to hit F3 more than once to hear it. No one would ever notice it in a mix, though. One says "slower". The other I can't make out. It might be "these are not the droids you're looking for".
