Serious potential. BUT

Since I’ve installed this and all the recent updates. My beloved Luis Martinez drum machine collection I rely on for almost everything, are crashing like crazy. IBassist has a ton of potential. I’d like to be able to use the bass sounds as a module. And it’s a tad flaky. The samples are amazing and the potential is huge. When it comes to improv jamming spontaneous bass lines... chosen harmonies and attack and so on for fills and ad lib is gonna be a tricky one. I love the sounds and it’s got the Luis Martinez groove. It’ll get there. From toms to pitched nots is a huge step.

The updates are funky in an un good way so I can’t enjoy it like I should be able to.

Developer Response

A new update is available v1.01, solving issues and adding new features.


Almost Fantastic!

Fantastic Idea ..but...there seems to be a slight lag between the Bass Sound and the Drums that are linked.(I own 4 of your Drum Apps, and they all lag a little behind.) I didn’t notice this at first. Other than that, yes it does Crash some and Freaks Out when using AUM sometimes. Works great otherwise. But, once you notice the Lag you can’t forget that it’s there. Please Fix This and you will have yourself something really Groundbreaking.


2018 APP OF THE YEAR! My vote, it’s that awesome! A Must Buy, Seriously!

I finally just got iBassist
Wow even thought I helped with beta, the final product is amazing!!!!
Jaw hit floor when I had Rock, Funk and Soft Drummers all synchronized with iBassist! Wow thanks Luis this app is truly amazing!

The ease of editing a line is incredible! I had a slap bass line going and just tapping notes in and out created amazing variations! Like listening to an all out Drum & Bass concert!!!!!

I love it!!!

Visit the AudioBus Forum, the Developer Luis Martinez is super awesome and helpful usually visits the forum when he has time from coding and gets users input and provides help.

This is the app of the year! Apple should award this to Luis, truly an incredible app!

I highly recommend this this app! Truly the best app purchase of the year for me.

It is worth every penny!
