Okay I will be absolutely as explicit as I can, and hopefully we can get this sorted. IMHO, it isn't all that fiddly, it's actually straightforward to my mind.
Steps to recording via ASIO for Logic, Cubase, and Nuendo:
1. Put ASIO Source & Destination modules into your Pulsar project. Have them inside your project BEFORE you launch your sequencer. You can adjust the number of channels by double clicking the ASIO modules, adjust them BEFORE you launch your sequencer. There are various ways to wire audio TO and FROM your ASIO program just keep this in mind:
a. ASIO Source is audio coming FROM your sequencer (for ie: mixing & effecting inside Pulsar).
b. ASIO Destination is audio going TO your sequencer (for ie: "Record to Disk" functionality or "perfectly cut loops" as you are desiring).
Notes: For Logic, I use the ASIO2 24-bit Source & Destination modules, I suggest using ASIO2 modules.
2. Start your sequencer program, of course leaving Pulsar open still. Setup the AUDIO section of your sequencer to use the same bit depth ASIO SCOPE driver (same driver used by all Creamware cards for ASIO). This varies depending on your sequencer. Check your sequencer's manual for more information.
Note: In Logic, simply check the "ASIO2" driver in the Audio Preferences dialog box, check 24-bit if you've used the 24bit modules in Pulsar, and select "ASIO Scope" in the pulldown.
3. Now that you have made a change to the audio drivers, you will need to restart your sequencer. You only need to do this step <b>once</b>; future sessions with your sequencer will look for the ASIO source/destination modules automatically (so be sure they are always included in your Pulsar projects from now on!) - if they don't appear in your Pulsar project then you might get a message from your sequencer (Logic does) telling you this when you start your sequencer.
Now let's test this a little. In your Pulsar project, wire ASIO Source 1&2 to a mixer (of course, the outputs of the mixer routed to physical outputs of the card so you can hear it, like normal). In your sequencer, load a large .WAV file - something like a minute long or longer, onto a new Audio track (and double check the Audio track is using the ASIO Scope driver). Press play in your sequencer, you should now hear audio out of the ASIO source and see meters in Pulsar! If you don't, then go back and double check your cabling & driver settings. Once playback works, continue here.
Note: You will get no Audio, or will not be able to select the ASIO Scope Driver, if your sequencer isn't getting digital sync. So, for example, if your Pulsar is slaving to a Digital desk which is turned off, such that Pulsar isn't showing a sample rate in the Sample Rate dialog, then you will have no audio in your sequencer. Make sure there is sync between all devices.
4. Okay now that audio works coming FROM the sequencer to the Pulsar environment, let's go the other way. First, create new Audio track in your sequencer (in Logic, double click a blank track, click and hold until a popup comes up, then select ie: Audio Track 2 from the list).
Select a region you'd like to record into, in your sequencer. (In Logic, this is, I believe, left clicking the start & right clicking the end position on the Time Bar at the top)
Arm the channel for recording - In logic click the little "R" next to the track so it turns red.
Press record in your sequencer.
Done.
Depending on how your sequencer is setup, it may loop between the points you have selected, creating a new audio track each time it passes through the loop (for, eg: multiple .WAV files of the same section, only with different knob tweaks, etc), or it may not completely 'trim' the loops, recording before & after the loop points too.
Hope that helps, I am sure there are people using Cubase who could fill in the Cubase-specific details.
