(back) Subject: Vox on separate chest? From: "Robert W. Taylor" <rtaylor@socket.net> Date: Thu, 7 Aug 2003 18:31:24 -0500   I've wondered if taking the Vox off of my 13 stop swell chest, and placing it on an unit chest would have any real advantage. (I just acquired a small vox chest) The change would permit the vox to be drawn, with its own trem, while the swell trem would be off. Now, when the vox is on, the whole swell chest is under trem.   The vacant space on the swell could be filled with several ranks I have on hand, but most likely, an 8' Gamba to fill out my string chorus.   Any comments from the group?   Regards,   Bob Taylor

The vox isn't used much outside of normal pitch, so it won't be unified to death. It is nice to have a separate trem for the vox, usually faster and slightly heavier than the Swell trem.   At 06:31 PM 8/7/2003 -0500, Robert W.

If it is, you'll need to create an "expansion chamber" between the upperboard and magnet, or the reed pipes will probably not speak properly.   Ross

From: "Paul Soulek" <pipeorganpaul@yahoo.com> Date: Thu, 7 Aug 2003 20:37:14 -0700 (PDT)   Okay...I'm buying some replacement chips tonight on digikey.com --- only there are two choice for what I want:   ON THE HEX SCHMITT TRIGGER (40106/4584/74C14) Same number, then a dash and a SOIC, TSSOP, or DIP suffix on the end. Which one do I want?   It's the same thing on the 4094 chip that I need (8 bit shift register). That gives the choice of either a TSSOP or DIP.   And the last chip is the driver chips, it gives the choice of SOL or DIP.   Since DIP is the only common one, I would imagine it's that one. But I wanted to check with people that would know before I do anything that I shouldn't...   Thanks for your help!!!!
