i've gotten clicks before when chaining two patterns together, right when the patterns change, there is a tiny click. i'll have to try the examples you wrote about though. steve >From: "machinedrum99" <machinedrum99@...> >Reply-To: elektron-users@yahoogroups.com >To: elektron-users@yahoogroups.com >Subject: [elektron] MD - Imperfect >Date: Mon, 22 Dec 2003 05:18:26 -0000 >MIME-Version: 1.0 >>X-Sender: machinedrum99@... >Received: from n20.grp.scd.yahoo.com ([66.218.66.76]) by >mc12-f26.hotmail.com with Microsoft SMTPSVC(5.0.2195.6713); Sun, 21 Dec >2003 21:18:35 -0800 >Received: from [66.218.66.160] by n20.grp.scd.yahoo.com with NNFMP; 22 Dec >2003 05:18:30 -0000 >Received: (qmail 30140 invoked from network); 22 Dec 2003 05:18:27 -0000 >Received: from unknown (66.218.66.216) by m20.grp.scd.yahoo.com with QMQP; >22 Dec 2003 05:18:27 -0000 >Received: from unknown (HELO n20.grp.scd.yahoo.com) (66.218.66.76) by >mta1.grp.scd.yahoo.com with SMTP; 22 Dec 2003 05:18:27 -0000 >Received: from [66.218.67.158] by n20.grp.scd.yahoo.com with NNFMP; 22 Dec >2003 05:18:27 -0000 >X-Message-Info: JGTYoYF78jFzUXo2j0A5BumkhsZQPIRG >X-eGroups-Return: >sentto-284773-7269-1072070308-artificialretard=hotmail.com@... >X-Apparently-To: elektron-users@yahoogroups.com >Message-ID: <bs5ur2+g9mr@...> >User-Agent: eGroups-EW/0.82 >X-Mailer: Yahoo Groups Message Poster >X-eGroups-Remote-IP: 66.218.66.76 >X-Yahoo-Profile: machinedrum99 >Mailing-List: list elektron-users@yahoogroups.com; contact >elektron-users-owner@yahoogroups.com >Delivered-To: mailing list elektron-users@yahoogroups.com >Precedence: bulk >List-Unsubscribe: <mailto:elektron-users-unsubscribe@yahoogroups.com> >Return-Path: >sentto-284773-7269-1072070308-artificialretard=hotmail.com@... >X-OriginalArrivalTime: 22 Dec 2003 05:18:35.0983 (UTC) >FILETIME=[0CD405F0:01C3C84B] > >Has anybody noticed inaccuracies in their MD?
