To adjust only the speed and not the pitch (in other words, to timestretch), leave the wheel alone and press only the left (|<<) and right (>>|) keys.

Woohoo! Feels like I have finally conquered an RPG. Finally made it work thanks to this final info.

I initially missed that there are 4 screens. At a glance it looks like only two screens that you toggle between. Would be helpful if the above instructions were put in the manual. I know they are redundant and that all the information is already there if one reads carefully but I am sure RockBox isn't deliberately designed to be a puzzle (especially since everyone has been so helpful in this forum... thanks to all you developers!!!! )

One thing still puzzles me technically: How did you guy solve a challenge that Steinberg couldn't get right in WaveLab v5? I used to always have to double the speed of my podcasts in WaveLab before tranferring to my player. But certain ID3 tags t would crash it (especially if they had artwork jpg). So I had to remove each tag both ID3v1 & ID3v3 plus artwork.

I suspect that your algorithm is superior too since it retains consonants rather than dropping a few (like Steinberg do)... am not sure about this but so far sounds great.

As you can see, you have made my listening to podcasts much much much easier. Thanks ever so much for being the first to get this right. By the way, anyone else interested in podcasts can download &/or hear my specially selected (and often edited) alltime faves from my page: http://jo.koan.net/freespeech

When I press REC on my e280v1, the UP/DOWN change from PITCH to SEMITONE, however at no point does pressing the UP or DOWN button actually change anything... UP takes you back to the track info display, and DOWN does nothing... no matter if it says PITCH or SEMITONE.

As a DJ, I do think PAUSE and REW within the pitch interface(especially since I have unused buttons) and cue point, (hold to set, press to jump) would be useful. I'd also like to see the scroll wheel be switchable to nudge too.

regardless... I'd just like to say how pleased I am with this function! I was pretty sprung on Rockbox already for giving me access to my file structure, crossfading playback, SDHC access etc ... but I've been waiting for fine pitch control (nudge too) for years, ever since I discovered my old 512MB SanDisk player had a few 5% pitch adjustments. THANK YOU THANK YOU!!

And thanks to sqgl for the link, looks like some good stuff in there! ;D

If the controls don't work correctly in an official build then it would be helpful if you could submit a bug report in Flyspray, so the devs can keep track of what's working and what's not.  Thanks!

corypark:
Thanks for the tip... I will ;)
