### 5/5 — Let’s get this party started, also!  Good delay/echo.

*2024-01-09*

First, it’s a really nice little echo/delay unit.  Second, for the developer, Pedro Yamada - to have a UNIQUE product, a singular FX app, just put a SECOND echo/delay in series with each of the ‘L’and ‘R’ delay/echo functions you have here.  I will pay an upgrade fee to get that modification to this original FX app.  I lost my favourite little dual serial echo app, and have been looking for a simple replacement, and this is it, if you add in a duplicate set of dials on the left of the fascia, and simply allow the user to introduce a second Left echo, and second Right echo, if they say, double-tap the dial to invoke it.  Or , have a new dial within the old dial, anyway you do it, it will be unique on the appstore.  I know, because I’ve scoured it.  

Sure, I can use a huge Audio-Unit ‘container’ and drop in two instances of their replica echo/delay to accomplish this, but it’s a hammer to crack a nut.  Your little echo/delay FX app, would be perfect, if it had this addition, and saves the user taking up a valuable extra FX slot in say GarageBand, just to get a serial echo/delay effect.  AND if you could make them last for ‘two bars’ as their maximum in effect?  That would be perfection.  Like now, the max if syncing, is 1/1.  I’d like 2/1 to be the maximum, if you get my drift?  Now, I own ‘Timeless’ by you know who, why would I not just use that?  Because it’s hard to understand.  I literally understand when I am staggering a couple of echo/delay sounds in series, what I am doing and what the result will be.  Multi-tap is a chore. !  I don’t understand how to visualise/conceive the resulting effect, is all.  So there you are, that’s your USP/upgrade version right there!  Good luck, I also just got the tremolo app you do.
